A paternal 1st cousin of mine, who could have and should have been a supermodel when it was a real thing, ended up marrying an asshole who never told her that he was a product of incest.
She had two clinically retarded children who will require care for the rest of their lives, and kinda gave her a life she wanted, minus having children whom are not mentally disabled.
The first boy did not physically present as mentally handicapped until it became clear that he was not reaching normal and expected milestones as a kid, and by that time, she was already pregnant with the second kid.
The husband was not physically nor mentally disabled, surprisingly enough, but even worse, he was a deceptive grifter who conned someone out of an experience that became unnecessary and was totally unexpected, because he conned my cousin into believing he loved her, didn’t disclose his genetic genealogy and the risks and known problem that such a history might pose for my cousin and her opportunity to say ,”No kids”, all for a Green Card.
The asshole had kids and an entire family, back at his country of origin, by the way. Also handicapped kids, with a legal wife, who actually believed he was in the US getting an engineering degree. The one who was getting the engineering degree was my other cousin, Dominick.
Incest is not normal nor is it a healthy way to establish and develop a normal and independent sexual-socio self, or the perception of that self. It is not a necessary practice in order to keep the human species going. We have long been past this.
Also, in present day, modern societies, as in for hundreds of years past, it is usually almost ALWAYS exploitative to someone or a group of someones, usually CHILDREN & GIRLS, and as exhibited in my poor cousin’s marriage and pursuit of becoming a mother, can ruin a total stranger’s life, if that stranger procreates with someone who themselves, are a byproduct of incest.
It matters not, whether or not the child who is a product of incest knows he or she is. What matters is that he or she is born into a society that has made it socially and legally unacceptable, due to very good and justified reasons, that have nothing to do with religious beliefs or morality, & those reasons are based on the study of genetics and DNA. The human species would not have survived or evolved, if incest were still acceptable socially and legally. It is abusive and ethically wrong to knowingly pursue a sexual relationship with a relative, kids or no kids as a result.
So yes. Incest is wrong as is the concept of eugenics, when used for creating a “master” race of people who all look the same. Eventually, that “master” race while perhaps not incestuous, will also confront problems rooted in the practice of only procreating with people who live in a certain geographic area, who look like alike in eye color and hair color, height, skin pigmentation, and who share similar intelligence, etc.
The optimal and desired results when considering genetics, race, intelligence, for me, and qualified experts, is resilience and proliferation through diversity and progeny resulting through that diversity. Ever wish you were taller, more athletic, smarter, had thicker hair, or stronger tooth enamel? Or maybe a bigger penis or didn’t sunburn so easily, making you susceptible to skin cancer? Or how about hailing from a family of drunks, and generationally so? It’s not a moral issue or even an anomaly, if you or your children, also become addicted, or even a surprise.
Ever consider how life would have been a bit easier if any of these traits had been in your genetic makeup or as importantly, had not been?
Well, perhaps if your ancestors and/or parents weren’t cousins or had married outside of their villages or townships, you would not have had these issues or would have been taller, or not had 10 cavities by the time you were 12.
Incest is not OK, and is not necessary and weakens the genetic pool, when practiced, for any reason.
NO, NOPE NEVER.
