Seeing the Yuri/yaoi kids at school might be the reason I hate anime and anyone who gets upset and starts saying "you just gotta watch the right ones". It was a small rural school and only the weebs were brave enough to think they could get away with that shit. They tarnished everything they touched, and everyone ignored them. I'm sure we had closet furries and other more heinous things, but this was the point in time where that shit wasn't tolerated or known and getting ostracized in the middle of nowhere where everyone knows you is a bad idea.
You wind up in the future troon squad. To answer the question, I think that shit is a symptom and not the cause. The cause is far more nuanced and complicated.
