Exposure to other viewpoints is good. No need to debate. And if you’re on a large instance, you’ll see that. Not everyone thinks alike, there are shades of gray. Discussion is allowed to happen but intolerance isn’t tolerated.
The tankie instances ban anyone for even asking questions politely that they don’t agree with. It’s a total monoculture and I assume they’re mostly still kids, because everything is black and white and can be solved without any nuance at all.
Mostly the people running and modding it are insane.
