Yaoi is trash 99% of the time but so is everything else I guess
It's just the experiences I've had as a fujo and with other fujos both IRL and online have made me really not want to have anything to do with them anymore, some of them also get really fucking crazy over super petty details like which guy should fuck which dude or (especially in the JP side) which one should be top or bottom
(they seriously get insanely mad over the ship name having the "wrong" order lmao), some of them really get triggered if one of their favorite guys is with a woman, and their overall behavior is also rather annoying, but no biggie
Besides I also hate how fujos make characters I like completely OOT just to fit their assigned uke or seme role, but again, no big deal (AUs exist after all), and it's not as common now as it used to be.
I like some yaoi every once in a while, and I really
enjoy some gay pairings, but I also don't want to make every single male friendship gay and sexual, sometimes they're much better and cuter as rivals or friends or what have you, you know? But fujos can't have that, so they hate you for not preferring the explicitly gay interpretation. Etc. etc.
