I read a chunk of his work like 15 years ago because one of my stoner friends was into it. I recall seeing shit like "women are weaker than men" or "women are trying desperately to prove they're not weaker than men, makes ya think dun it?" typical reactionary man shit, I recall various shit about queer people being vaguely disgusting to him, including some episode of visiting a gender clinic but 'coming to his senses' or similar disgusting crap.

I'm gonna guess you're not a woman, and probably hetero white? people say things in certain ways and it indicates how they think about you. If you're in a majority the remark "Oh I didn't think someone like you would enjoy that" is almost certainly just innocent expression based on how someone has modelled you as an individual, if you're not it's very likely to be be someone excluding you as a class of person. you get sensitised to spotting shit like that in how people talk/how they behave and seeing the broader picture.

Keep in mind we're talking about someone who bombed broadly random individuals. He was a sadistic, broken, piece of shit.
