The only explanation I can think of is degenerate porn continuing to rot people's brains. We all know that's how the tranny problem got out of control, and once someone's sexuality is fucked up like that beastiality isn't that much of a jump.

Nail on the head.

I remember years ago when Overwatch started gaying up their characters, a common response from people was "Well, these characters are in all sorts of gay acts in the porn, so why not just make it canon?"

I was gobsmacked at the amount of people were basically saying: because this happens in porn, it's fine if it happens in canon.

There's another property I'm only tangentially familiar with called RWBY or something like that. Apparently in fanfiction and whatnot two characters are constantly being "shipped" together, and so I think that also became canon. And people were praising it because their erotic fanfiction was made canon.

That's kind of where we are now with media.
