Sure, the weak of heart need solace in these dark times, where anyone might have a different opinion than their own.
But, seriously, you're right that 'crap I don't want to hear' should totally be handled by individuals making that choice, rather than mods banning people.
Honestly we should ban communism on non communism communities. However I'll settle for just ignoring them.
Banning someone for not having radical beliefs is just silly. We should boycott lemmy.ml as they are effectively a propaganda machine. (Try to switch to small instances)
I don't personally think it should be banned. I find it fascinating to be able to encounter people with wildly differing ideas to mine. I switched instances aswell because the previous one didn't federate with lemmygrad and hexbear.
