(Here is a PDF version of the full text) This is for the benefit of friends or family of romantically involved siblings, who may have recently discovered their secret. Though I’ve used “incest” in the title, I won’t continue to use the terms “incest” or “incestuous,” I will use
“consanguinamory” and “consanguineous” (pronounced “con-sang-gwin-
am-or-ee” and “con-sang-
gwin-ee-us). “Incest” is too loaded a word for intelligent discussion, and I only ever use it for sexual abuse.
If I say “consanguinamory”, assume I am talking about consensual sex. (I’m going to assume that the couple is opposite-sex, but most of this also applies for same-sex couples.)
Remember: there’s a difference between love and abuse. This might be long, but bear with me. All of your concerns are about to be addressed. If you truly love them, you will have the patience to read this.
- INTRODUCTION First, stop and take a breath. I know that this must be a lot to take in. I seriously doubt that you’ve ever sat down to consider the possibility of this happening.
I don’t expect you to be calm, but I do expect you to care enough about their well-being to seriously consider what I’m about to say. Did you discover them accidentally? If so, talk to them individually –
with an open mind – and make sure that there was no coercion. Ignore the taboo nature of what you just found out. If you have no evidence of coercion or manipulation, then do not try to project abuse where there is none, and do not force them to internalize your own sense of what’s “taboo.” Why would you ever want to burden them with so much unnecessary guilt and shame? Talk to them together, and get the story from them, calmly. See how they act together. Remember to treat them with respect, especially if they’re already adults; it’s what you would want for yourself. Did they come out to you on their own? Then there’s even less chance that there was any coercion involved. In fact, coming out to you is one of the bravest and most trusting gifts they could ever give you. Not only is their love extremely taboo, but even if they are adults, in most places on Earth they could be thrown in jail, possibly for the rest of their lives. You could get them thrown in jail. Every person they tell is a potential threat who could ruin their lives forever, getting them locked up for years and permanently placed on the sex-offender registry. And yet, despite all that, they told you. They could have lied – it wouldn’t have been easy, but they could have – but they told you. However much you thought they trusted and loved you, they just proved that their true trust and love is greater.
If they say that it’s consensual, and there’s no evidence it isn’t – especially if they came forward on their own – how can you still assume that no person could consent to it? How can you possibly disrespect their intelligence and agency so much? Have you ever had any other reason to doubt that they are of sound mind and soul? Then why should this one thing counteract years of personal experience? Did they hurt anyone? Of course not. If you think there must be something wrong, it’s because that’s the story society has been spoon-feeding you. Consider: if one of them was adopted – if they weren’t genetically related – would you still feel as uncomfortable as you do? Because if you wouldn’t, then there’s no good reason for your discomfort now; socially, whether adopted or not, their relationship would be the same. If they weren’t even raised together, then in no way are they family, though they are blood relatives. Ignore for a moment the particular, taboo nature of their relationship. Just consider them as individual people. If your daughter/sister/friend was dating a man like her brother, knowing everything you do about him, would you be displeased, or happy? If your son/brother/friend were dating a woman like his sister, knowing everything you do about her, would you be upset, or glad? If you are their parent, unless you’ve done an awful job of raising them, my guess is that, before you found out, you were quite proud of them. Well, they’re the same people now, the same people who made you proud. Wouldn’t you want your daughter to date a man who made you as proud as your son? Wouldn’t you want your son to date a woman who made you as proud as your daughter? Aren’t they more to you, and to each other, than just their genes? - MENTAL HEALTH Society has taught you to feel a certain way about consanguinamory. It was handed to you, and you accepted it without much thought.
You’ve probably never met anyone who was openly sexually involved with a close family member. This has allowed you to go around without seriously considering what such a relationship might look like, how it could work, and how you should feel about it.
It has allowed you to absorb the limited perspective put out by the media, giving you a narrow, stereotyped view of what’s possible. You have been listening to
only one side of the story your whole life.
Just because you don’t know that you’ve met such a couple before, doesn’t mean that you haven’t met one. In fact, as you
follow your family tree further and further back in time, the probability that
you will find at least one consanguineous couple approaches 100%.
Self-reported surveys have found that as much as 10% of college students have had consensual sexual contact with a sibling (mostly childhood experimentation). (If we extrapolate this to the whole population, this equates to about 30 million people in the U.S.) The fact that a couple is related tells you exactly nothing about what their relationship is like, nor whether it is consenting or not, nor whether it is fulfilling or not. Each of those things is independent of their blood relationship.
The cultural stereotype of such relationships is that they are dysfunctional, self-destructive, and abusive; anyone who willingly participates must somehow be mentally ill. Besides this view being incredibly condescending, it also has no meaningful basis. What is considered “healthy” and “unhealthy” changes, and is very subjective. On what standard are we to decide what constitutes mental “illness?” Is it that they’re doing something they know society disapproves of?
I don’t think any reasonable person thinks we should use the preconceptions of the majority to decide what constitutes mental illness. It must, then, be that the behavior is self-destructive, or causes them to destroy the lives of others.
Do you see anything indicating that those things are happening? Aside from their experience of bigotry, do they seem unusually disturbed?
Are they lashing out at themselves, at each other, or at you? Are they unable to operate normally in a social environment? If not, then you have no reason to think they are any less mentally healthy than before. In fact, their love may have made them
healthier, by bringing them fulfillment and peace.
“From a scientific perspective, we do not know what constitutes normal childhood sexual behavior or feelings. […] Sexual behavior varies drastically among different groups of people due to their moral beliefs, values, social class, and culture. Sexual feelings and behaviors also vary widely among youth due to individual differences and variations in development. […] Some of the behaviors mentioned above are harmful. However, many are socially unacceptable because they would be classified as immoral or indecent by many people, not because they are harmful.”
As I’ve said, you’ve probably already met a consanguineous couple. They couldn’t have stood out as any more dysfunctional than the average couple, or you would have become suspicious that something was wrong.
Unfortunately, prejudice keeps people in the closet, which perpetuates ignorance, which itself perpetuates prejudice. You have been given the rare opportunity to examine your own assumptions, and
break your own cycle of prejudice. Most people have never gotten that chance.
The “pedophile” label has long been used to brand sexual minorities as deviants, as threats to society and to our children.
Homosexuality has long been heavily attacked as pedophilic, and in the past when people had limited experience with open, healthy same-sex relationships, they believed the propaganda. Now that so many homosexual couples are out in the open, we realize that there is a clear difference between the consenting majority, and the predatory minority.
Even today, opponents of legal rights for homosexuals try to brand the gay rights agenda as pro-pedophilia. There is
a homophobic Neo-Nazi “vigilante” group in Russia called “Occupy Pedophilia,” but it isn’t pedophiles they’re targeting: they target young gay men. They go around torturing them, sometimes to death, and use “fighting pedophilia” as their implicit justification.
It is the same for consanguinamory. The vast majority of cases that come to light are the most unhealthy. (In
the previously quoted summary of studies, only 30% of respondents answered that their reaction to sexual contact with a sibling was “negative.” Of that 30%, 25% were non-consensual. The remaining 5% may be due to stigma and shame.)
Those in healthy, fulfilling relationships never come forward, and we only see them in the news when they are caught and thrown in jail. The consanguinamorous are lumped in with a predatory minority, and because of the closet, the public buys it.
Just because these siblings love each other, it doesn’t mean that they want to have sex with any other relatives, and it doesn’t mean that they are pedophiles. Despite the propaganda, their relationship does not automatically mean they are abusive and emotionally damaged.
Besides,
so what if every
other consanguineous relationship in history has been abusive and emotionally damaging?
We consider people as individuals, and don’t punish them based on the sins of others. Even in murder trials, attenuating circumstances are considered.
If murderers get the benefit of the doubt, if murderers get to be treated as individuals, then why not these siblings? Even if every other relationship like theirs was damaging, that doesn’t automatically mean theirs is.
If they are the only loving, consenting blood-related couple in the world, then that’s all the more reason to treat them with respect and dignity. - ABNORMALITY However, they are not the only siblings to have a consenting, loving relationship. It is not some newfangled idea. Societies’ attitudes towards various sexual relationships – especially familial – have changed all throughout history.
They are in illustrious company, among some of the greatest people to ever live. These are just a handful of the examples known, and there are certainly many more lost to history.
- Japanese emperor Bidatsu married his half-sister, Empress Suiko.
- Korean king Gwangjong also married his half-sister, Queen Daemok.
- Inca emperor Huayna Capac married his full-sister, Coya Cusirimay.
- Siamese king Rama married four of his half-sisters. (This was in the 1800’s, too.)
- An aristocratic Athenian woman, Elpinice, was married to her half-brother until she divorced him and married another man to settle a family debt. Upon her death, she was buried with her brother, not her husband. In Athens, familial relation was considered to be passed on through the mother, so if two siblings did not have the same mother, they could get legally married. In Sparta, it was passed on through the father. This shows how contrived and arbitrary our concepts of “blood-relation” and “incest” are. Even now, our taboos are pre-modern.
- Because of the unique, divine status of pharaohs in Egyptian society, it was common for pharaohs to marry within their immediate family, to preserve the purity of their divine bloodline. Pharaoh Tutankhamen was both the product of a sibling marriage, and himself had a sibling as his wife.
- The practice continued under the Ptolemies, and Pharaoh Cleopatra was married to each of her brothers until they died, leaving her the sole pharaoh. By then, the practice of sibling marriage had spread to all classes of Egyptian society, providing the only case in history where full-sibling marriage was not only allowed, but encouraged. As much as a fifth of all marriages were sibling marriages. The practice continued under the Romans, but was eliminated by Roman pressure: the Romans refused to make anyone who married a sibling a Roman citizen. Egyptian society survived all of this sibling marriage, and is still around today. They have the same number of toes and fingers as everyone else, so clearly it was not as dangerous as the stereotype says.
- For similar reasons as the Egyptian pharaohs, the Seleucid emperors also started to marry their sisters. The first such empress of the Seleucid Empire was Laodice IV. She married her oldest brother, whom accounts say she loved dearly, and bore him a daughter. When he died, she married her second oldest brother, and bore him three children. When he then died, she married her youngest brother, and bore him two children. There are no records stating that any of these children were anything but healthy.
- It was common practice in Hawai’ian society for royals to marry within their own family. The practice was actually encouraged by Hawai’ian elders. When Christian missionaries came to Hawai’i, they tried to crush the practice. The last Hawai’ian king to have a consanguineous relationship was Hawai’ian king Kamehameha III, the first Christian king of Hawai’i. However, he didn’t succumb to the wishes of the missionaries. At an early age, he had fallen in love with his sister Nahi’ena’ena, and wanted to marry her. Because of opposition by the missionaries, he did not, but he also held off marrying the preferred choice of the missionaries for many years. “Bingham learned that even after King Kamehameha III of Hawaii accepted Christian rule, he slept for several years with his sister, Princess Nahi’ena’ena — pleasing their elders but disturbing the missionaries. They did it, says historian Carando, because they loved each other.” He only married the wife favored by the missionaries after his sister had died.
- The love between Artemisia II and her brother Mausolus was so profound, they became symbols in Greek writing of love and devotion. Mausolus was a rich Greek vassal of the Persian Empire in what is now Turkey. Under the reign of he and his sister, their territory flourished, and they built many monuments. Their final monument was so glorious, it became known as one of the seven wonders of the world: a giant tomb, to house their ashes. (It’s from “Mausolus” that we get the word “mausoleum.”) When her brother Mausolus died, Artemisia’s grief was so great that she ritually drank a bit of his ashes every day. She ruled well for two years, but eventually wasted away from sorrow. Her ashes were sealed in the Mausoleum with what remained of her brother’s. Their tomb would last for over a thousand years, amazing everyone who saw it.
Not only are they in glorious past company, but in beautiful present company as well. In the past, only royals and aristocrats could break society’s rules and marry whom they wished. Why should the right to love whom they wish to love be denied to the common man or woman? Romantic sibling relationships are much more common than most realize.
Many of these relationships, when allowed to flourish, grow into something astoundingly beautiful. A sister:
“We all love for the same reason: our hearts and souls tell us that the person we are with is the right one for us. Follow your heart, listen to your soul. When you know your heart, mind and soul speak as one, it’s right. Love never judges anyone, so don’t judge until you fully understand. We may be related, but look past that, see us for who we are. He’s my brother, yet he’s also my bear. He’s a Grizzly in his fight to give disabled people the right to lead as normal a life as you and me, yet my Teddy Bear when he’s in my arms. Don’t discriminate [against] us, don’t judge us. We have a right to live and love, just like everybody else does.”
- FORCING THEM APART You may wish that they would just find other people. There are plenty of non-blood-related fish in the sea. If they did that, it would certainly make things easier for
you, wouldn’t it? You may even be able to convince yourself that it would somehow be easier for them, too. Well, why
should they find other people?
Do you have someone you love? If so, why don’t you find someone else? It’s easy to see that it’s not so easy. If you knew a bisexual man who was dating another man, would you tell him that, because he has “more acceptable options,” that he must date a woman? The “homosexuality isn’t a choice” argument is strawmaning: it serves as a nice talking point, but that’s not ultimately why society now feels that homophobia is wrong.
We’ve come to understand that love doesn’t always fit the conventions proscribed by society; that it is morally wrong to police people’s sex lives and love lives; that society is better off when we nurture people’s natural love. A bisexual person may be capable of loving someone of the opposite sex, but that doesn’t mean they will. No-one chooses who they fall in love with.
It is no different for siblings in love. Besides, have you stopped to consider the consequences of forcing them to break up? People think only of the consequences of letting siblings stay together, but not of destroying their relationship.
Consider: how will breaking them up, causing them misery and pain, shaming them, and policing them make their relationship “healthy?” Even if you think it’s “unhealthy” now, their relationship is guaranteed to be much worse after that kind of trauma.
They’ll remember what they had, they’ll remember the pain of its loss, they’ll remember the judgment, they’ll remember the shame, and they will probably know that they still love each other. What kind of family dinners do you expect with that kind of angst floating around? They may in fact choose to never see each other again, because it would be too painful.
What if they shun your judgment and shaming? Many consanguinamorous couples, when facing judgment and intervention by friends and family, break off all ties with them for the sake of preserving their own relationship with each other.
If you really do care about them, and also want to be part of their lives, learn to at least tolerate their love. Better that you have a presence in their lives. Don’t force them to choose between family and friends, and the love of their lives.
- RELATIONSHIP INSTABILITY Now, there is one legitimate concern regarding consanguinamory: won’t introducing sex and romance destabilize the family dynamic? What if it ultimately doesn’t work out? Won’t that make it difficult to go back to being just family for them?
The short answer: not necessarily. Now for the long answer. First of all, yes, it might, but many people pursue love at the risk of existing relationships, and we don’t begrudge them their pursuit of happiness, even if risky.
No truly good things in life are gained without risk. As a culture, we even romanticize such risky pursuits of love. I would argue that, aside from the threat of social stigma breaking them apart, they are actually less likely to break up than other couples. Assuming they were raised together, they’ve already had decades to get to know each other, most of it probably non-sexually.
Imagine if a man and woman lived together for sixteen or more years, without any sex at all, before they decided to be romantically involved. We would all consider that comically conservative, and yet that is the kind of experience these siblings have had. Even when romances do end explosively, they can still go back to normal, given time and space. There are couples that have broken up very dramatically, but after having a couple years to themselves are able to go back to being friends.
Even if these siblings do ultimately break up, given all of their prior experience as siblings, the common familial relationships, etc., they should be much more likely to eventually get back to being friendly than non-related couples. They would have more motivation to.
Remember too, not all romances end explosively. Some marriages end after over a decade, on amicable terms. If a relationship ends, the destructiveness of its end is related directly to the destructiveness of the relationship itself.
What destroys a relationship in such a way? Lying, abuse, lack of communication, emotional unavailability, bad conflict resolution skills, lack of respect, lack of appreciation, etc. Since you know the couple, you should have some idea whether they have problems with any of these things in their lives.
If you are their parent, then you are in a unique position to ensure that they both treat each other with respect, empathy, and honesty. You have an interest in their relationship being healthy in the long term, and you also have the power to help that happen.
Don’t assume that their relationship as siblings and their relationship as lovers are mutually exclusive. It’s a common, false assumption that they must be, but the personal testimony of people in such relationships refutes it.
I doubt they fell in love because they were bad siblings, but more likely it grew out of an especially close sibling relationship. We all acknowledge that people can serve multiple roles in a relationship, being both best friends and lovers. Well, so it is that they are best friends, lovers, and siblings.
Each one of those relationships strengthens the others: their relationship becomes greater than the sum of its parts. Even if familial and romantic love were mutually exclusive, who are you to decide which of those options is best for them? So they happened to be born as siblings. Why must that chain them the rest of their lives? Maybe they will be better as lovers than as siblings.
As consenting adults, they get to decide which kind of relationship makes them happiest. - HEALTH OF THEIR CHILDREN Assuming you’re okay with all of the points I’ve just made, you may still have one objection: what if they have babies? This is one of the last refuges for those who can’t quite justify banning consanguinamory, but still want to.
After all, what about all the stories of monster babies? Well, there are actually very few of those stories, they are an over-publicized minority, and that stereotype goes against actual scientific and historical evidence. These siblings may already have a child. They may be pregnant. They may be planning on having a child in the future. You might have even found out about it because a pregnancy or genetic test of a child brought it to light.
Once again, I must ask you to calm down, and listen carefully to what I’m about to say. The feelings you have are coming from a lot of cultural baggage and stereotyping, again. I won’t deny that the risks are higher than for the general population, but they’re not nearly as bad as you hear, and slightly elevated risks are never any reason to curtail a woman’s basic rights.
One hears an ingrained, “But it’s unnatural!” argument quite a bit. “Inbreeding” is not “unnatural,” as many would claim.
Many species engage in consanguineous mating in some form or another, and it can have both positive and negative effects, depending on the circumstances. Sometimes,
species even evolve a resistance to problems from “inbreeding.” In nature, as in society, things are always more complicated than a blanket judgment can capture. If we should force people to only have babies with people that are distantly related from them, for eugenic reasons, then why stop at prohibiting consanguinamory?
Why not forbid all sex between people of the same race? Genetic similarity within a population can still be great enough that genetic diseases are passed on –
just look at Tay-Sachs.
Of course the idea is ridiculous, but it just follows the logic of policing women’s uteri to minimize genetic disease. “[…] [S]cientists have rejected the explanation that [the] incest taboo is a social mechanism that reduces the risk of congenital birth defects. One of the reasons is, findings have concluded that recessive or defect-carrying genes in a population may increase or decrease in instances of inbreeding. The frequency of birth defects depends on the availability and effectiveness of healthcare in a population. A recent genetic report also stated that children of unrelated parents have a 3% to 4% risk of having serious birth defects, while the offspring of first cousins have only a slightly higher risk of about 4% to 7%.”
We can extrapolate from this that for siblings, it is at least 7%, and probably no higher than 10%. This is lower than the risk of birth defects for women over the age of 35, which is 12.5%. I have also
written about how new scientific discoveries are illuminating why, over many generations, having children with blood-relatives can have an effect on a population.
It’s not what most people think, it’s not as threatening as most people think, and more importantly, we may soon be able to fix it. Whether considering the genome, or the epigenome, a single generation can be completely inconsequential. All of the risks are
population-wide risks: the chances that a random sibling couple would have a child with defects are that high, but these two siblings are not a random couple.
They are a specific couple, with individual genomes. Their family history of disease is specific to their family. Those things tell you much more about their chances than some randomized study.
They may, in fact, have a lower probability of defects than the general population. Either way, we do not, as a society, agree with eugenics, and for good reason. We do not espouse the views of racists who spent decades sterilizing the poor and black in the U.S. They’ll have to care for the child, it is her body, it is their risk to take. It doesn’t matter whether you approve of it on a “massive scale” (which wouldn’t happen without society forcing people), all that matters is whether it would be okay for
this specific couple.
You’re probably also worried about how the child will deal with the taboo nature of its parents’ relationship.
Isn’t it better that a child grow up in a normal family? This is the kind of reasoning that punishes all sexual minorities for the bigotry of the majority. Not only do they have to deal with the derision of the masses, but now they have to give up their own children
because of that derision?
No enlightened person in this day and age would argue that we should take the children of same-sex couples away from them and have them raised in “normal” families. It would be barbarous, and yet there are homophobic reactionaries who argue against same-sex adoption with a similar argument.
We should never let the bigotry of others police our families. A child can learn to deal with ostracism, as long as they have a good support network at home, but no child can learn to live without experiencing love.
Isn’t it better that this child grows up in an “abnormal” household that loves them dearly, than a “normal” one that doesn’t? - CONCLUSION Here are refutations of many arguments people make against sibling consanguinamory. It’s a good addition to what I have just said. This quote from the article is especially apropos:
“There are siblings who are together right now, providing each other love, comfort, support, or their first sexual experience in a safe and reassuring environment. The biggest problem with sibling consanguinamory seems to be the prejudice and sex-negative attitudes of others. In most cases, trying to force consanguinamorous siblings apart only makes things worse. It can be a mutually beneficial way of bonding, expressing their love for each other, learning, and discovering their sexuality; it may even be a beautiful, lifelong romance. Let’s not let ignorance cause needless concern or repression.”
Don’t be ashamed of changing your mind. Other people have had to walk the same intellectual and emotional journey. Don’t be ashamed that you were once wrong. Better to grow as a person than cling to terrible beliefs out of a misplaced sense of embarrassment and ego.
Let yourself grow, for the sake of your child/sibling/friend. You may think you have nothing left to learn, but everyone can learn something, and everyone can teach something.
This is their moment to teach you. Here are some extra resources:
