Yeah, staying away from the MRA/PUA sites for months has helped. The "manosphere" is (was?) one of those things I had a morbid fascination with and it was not good for my mental health or views of malekind, lol. You made an excellent point about "human first" and that's really where all bigotry originates from, the notion that people are something other than fellow humans first.
PUA is "pick up artistry", right? Why would that necessarily be linked with sexism or rape apologetics. There's got to be communities which aren't, right?
