Me too, niece aswell. I find this strange. I can marry a man, I can have children with him, I can even become a combat helicopter, but I can not fuck my sister or cousin. It does not violate my rights and freedoms? Is there any organization like lgbt that is fighting for my right to have sex with my hypothetical sister or daughter?
I've posted this elsewhere, but it's worth posting again.
Patreon's rules regarding incest have nothing, zero, zilch, nada to do with whether incest is legal or not. It is perfectly legal in the United States to create and sell incest-related erotic stories, pornography, movies, etc. Actually, it's perfectly legal in the US to create and share erotic fiction and games--even movies--depicting underage minors having sex (as long as the actors are not underage in real life), although probably unwise to attempt to profit from it in this day and age.
Patreon did not ban and forbid incest because it is
illegal. They forbid incest, rape, mind-control, etc, because of pressure from both PayPal and even more so by pressure from the venture capitalist investors who do not want Patreon's "brand" to be associated with taboo content.
And yes, there are many organizations fighting for the rights of adults to enter into
consensual incest (consanguinamory). Just google it.
PS, for the record, I'm not big on making incest legal. It's not the "birth defects" reason (which is a myth anyway), but because it just seems likely that, even if two related adults can claim to be entering into a consensual sexual relationship, one of the partners may have "groomed" the other partner (daughter/son, younger sister/brother, etc) while living in the household. Laws forbidding incest protect children. But if two adult siblings are in love and want to spend the rest of their lives together, I'm not going to judge them.
