It's the main reason I gravitate so much towards lemmygrad. Their zero-tolerance stance on fash shit (plus being defederated from literally every problem instance by dint of being openly communist) allows you to have actual conversations with people without having to explain basic morality every three seconds. They're pretty tolerant of differing ideas as long as you're not parroting fascist talking points and even then they'll usually put in a good faith attempt to explain why what you're saying is fucked up and give you a chance to self-correct.
Sadly a lot of the federation is a lot less good about this, where anything even remotely political turns into a debate/slapfight where nobody feels good at the end of it and nothing really gets done. Some people are just useless trolls who shouldn't be engaged; not to mention the groups actively trying to balkanize the federation.
Plus if you think this place is bad. Mastodon... I made a post about them earlier but if you respond to any post without heaping praise you just get instantly blocked. They're a great platform but good god is the culture there just obscenely toxic to conversation.
