Because Donald J Trump is their guy. He might well win.

I’m happy to let mods carve out a bunch of niche communities with their own preferences. The fediverse is a big place. If you don’t like instances that are protective of LGBT+ folks you’re cutting it down a bit, but genuinely, you seem to be deliberately picking topics that troll the specific community you’re posting on, then you complained that they took it down. Post where your post will be welcome, stop complaining when you post where you already know it’s not. Reddit and twitter are pretty right wing and troll friendly. Maybe you’ll be happier there.
