I’ve always found that so stupid yeah. “Cop killing” is always painted as this ultimate evil and so much worse than killing a regular person, especially in all the copaganda shows. But theoretically the whole reason cops have so much legal leeway and can use so much force and whatnot is because they’re taking on a risk by putting themselves in the line of duty (even though you’re actually more likely to die as a pizza delivery driver).
join-lemmy.org has a list of instances you can join. If you just want to look through a list that’s a great place to browse.
If you’re looking for specific recommendations I’d say lemm.ee is great in terms of moderation, they don’t overmoderate and tend not to defederate from many places so users can kinda choose themselves whether or not to block an instance. Dbzer0 is similar, it’s the instance with the big piracy community which .world blocked, and the admin is also great.
Both of those are in the top 10 communities in terms of size though iirc, which ideally people would avoid the biggest instances and join smaller ones to try and prevent centralization like what happened with .world communities.
Lemmy.zip is also great from what I’ve heard, and while it’s not small, it’s top 20 instead of top 10 at least.
