why are some BL readers so aggressive?

idk if u can really call this a hot take,but yaoi readers need to stfu and really understand who they are defending in a story, like what the fuck are some yaoi readers so aggressive against people expressing opinions about a controversial book? for example Jinx, some of them readers have serious issues which understanding the the ML did a bad thing, such as mentality and physical abuse the MC but once someone bring it out they start cussing and being aggressive saying some half ass excuse why JJK(ML) acted that way. i understand liking or enjoying a toxic book, but defending a character who clearly did some wrong such as rape or abuse shouldn’t be tolerated even with being fictional or not.
i would also like to hear your thoughts on aggressive readers.
