I’m just going to say try making an account on the unilem.org instance, from there you’ll be able to access all instances from the fediverse. It’s about as politically balanced as they get since they almost never defederate, it doesn’t have very many communities though so you’ll have to find those on other instances, by the way if a community from another instance doesn’t appear in the one that you’re in, go to the search bar in the communities tab and type ![community name]@[instance domain] and assuming that you typed it correctly it’ll usually sync it and then you can subscribe to it.

Since unilem hasn’t defederated any of the big instances you’ll very likely have access to all communities on Lemmy.
