I've been on a bunch of trans servers, and a bunch of leftist servers. All trans servers ALWAYS devolve into a bunch of morons yelling at each other over weird as fuck drama and competitions on who's the most depressed person on there, which ends up being toxic as fuck to everyone. All leftist servers are filled up by either insufferable libs or insufferable tankies who take themselves so fucking seriously they will throw Mao quotes at you and call you "counter-revolutionary" cause you posted a meme.
Fucking burn it down.
I think your mileage really varies depending on how well moderated it is. Trans servers do tend towards becoming a bit of a pity party if people aren't actively promoting a more constructive culture, but I feel like I've had a good experience on some of those.
