> Seeing a woman being gang raped, choked and beaten, "consentually"? That's a new problem.
That is not that new either, BDSM has been a thing for decades. "Histoire d'O" for example came out in 1975, the literary work it's based on is even older. And the panic back then about these books is exactly the same kind of bullshit we're seeing today.
> The question is how to prevent that harm without depriving adults of their rights and liberties, not whether such a thing is harmful to a child's future ability to form healthy relationships.
Teach your kids about sexuality from early age. That also helps cutting down on cases of sexual abuse - think of all the clergy and sports trainer scandals. A lot of these failed prosecution or went on far too long because the kids lacked the vocabulary to describe what happened to them, or didn't recognize that what they went through was wrong.
The problem is, anything veering into this direction is immediately attacked by Conservatives, religious extremists and the likes.
