One thing i have to add because it's a perspective that seems to be missing here:
I am a straight dude from a moderately conservative European 3rd world country. And i find the infighting in the lgbtq community incredibly stupid, for one simple reason. If any of you lived here, you would certainly be discriminated and shunned by most of society, probably disowned, and maybe, if you're especially unlucky, stabbed.
And to me the idea that ace people or bi people aren't "queer enough" is kinda laughable, since it's so obvious that all those people fight the same fight. And in places where it's partially won, and especially in queer echo chambers(which Tumblr honestly is), it's possible to forget that.
