Why has purity culture taken over BL!?

I've noticed over the past few years that the fujosphere has become way more... virtue-signaly?? Like you can't even enjoy taboo subjects anymore without people whining in your ear!! At first it was funny but now all I see is people complaining about problematic this problematic that. BRO LET ME WANK IT TO WHAT I WANNA ヽ(`Д´)ﾉ WHAT HAPPENED TO EVERYONE READING THINGS LIKE KS??
