Because the implication here is that she thinks having sex with black men is more degrading/humiliating and getting beat up by them is like, more "savage" or something than other races
My liberal friends all disagree with me and thinks I'm kinkshaming, being racist myself, or invalidating her "preferences" or something (which I think is usually also racist, having racial preferences unless there's some shared culture/experiences)
some people take "don't yuck" as like an immunity to criticism, i thought it was just like, don't harrass someone who isn't hurting anyone. we don't have to protect partakers from the implications and social context. schoolgirl outfits being a product of inappropriately sexualizing teens is not a discussion an adult schoolgirl-outfit-fan deserves to be insulated from
I've known people under that umbrella across a couple different cities to wield that exactly as 'immunity from'; hence why I don't typically fuck with kink communities like that anymore
