Cuckold/Interracial Cuckold/Beastiality Porn -
You might be interested in why so many white guys are into interracial garbage, and it's mostly because - as much as you try to deny it, lefty bastard - everyone's still fucking racist, to some degree, even if unlike Sup Forumstards like us.
The white brain still sees blacks as inferior and more savage, because of their origins as slaves. In a way, the rush one gets from interracial porn is the same as the one from beastiality - it's the rush of seeing something inhumane happen.
It's why there's a lot less white guy on black girl porn, since the appeal in there is the reverse - but surprisingly, a lot of black guys have a fetish for getting dommed by white guys, in a reversed racial form of this.
Oh, and the BBC crap comes from this fountain too - same reason beastiality porn uses horses a lot, so porn focuses on pretending they're bigger by cherry-picking actors.
The reason size is less important in white on white normal porn is because the main character there is supposed to be a self-insert for the viewer, different from the interracial where the appeal is the same as cuck shit.
Hentai/Japshit - I'm not going to pretend japshit doesn't have the same risk - the porn slippery slope is real, and the japs are known for loving their fucking traps. You could argue it's a little less worse since there's a lot more still pictures and self-inserts, but you're still subjugated to the societal pressure and the slope will still happen.
Trapping/Crossdressing/Forced Feminization - The ultimate cuckery. This is the point the male absolutely gives up on any responsibility as a man and decides to simply become a woman and avoid all the problems above, while simply engaging in his autogynephilia openly. This is bad, fuckers, and it needs to stop.
Porn is degenerate, a jewish invention and needs to be stopped.
