So what's the problem? It's a ban-happy three-person mod team shaping a community. There are other communities with the same explicit subject. When a community's mods move it in a direction you don't like, you join or make a different one, and the nature of Lemmy means they haven't even camped an important community name.
It's not even a particularly tankie sub, there're posts calling Russia warmongers still up and at +82. Seems like most of the removals were posts trying to pick fights. And while tankie bashing is often fun and warranted, it's not really extreme censorship to say that's breaking a rule saying "everyone should feel welcome here".
