Because it's "leftist socially acceptable elitism". The faggotts present themselves as superior: they are supposedly more "open minded" than everyone else(because they play with feces and cut their dicks off), supposedly more "emotionally and sexually secure"(because they play with feces and cut their dicks off), more "progressive"(because they play with feces and cut their dicks off) etc etc etc. It is acceptable(amongst leftists) for them to be incredibly condescending without having to back up the claimed superiority in any actual way. And they jump on the bandwagon when they are young and lazy and get to spend their entire lives telling themselves they are truly elite and making "progress for humanity" through this stupid gimmick shit. In doing so they get what I call the "pseudo ego feed": they do not actually outdo anyone ever, but goddamn are they fucking condescending. And if anyone says otherwise the faggotts get to hide behind the term "hate crime".
I've yet to meet one homo who is OPEN MINDED~! to the idea that there might be something wrong with them since they play with feces and mutilate themselves.
