To add an anecdote,
I had a conversation with u/bandhmo when they were still hanging about AZ. In that conversation we talked about the higher rate of communists here, and I said I's was comfortable with them, in fact I found it refreshing, a sort of contrast to constantly seeing the same old Neo-lib, conservative, or libertarian talking points on places like Reddit that I used to frequent.
This, I think, is an under-evaluated element of the Lemmy network and its developers. It'll be down to network effects and structure to see how the communists influence continues if Lemmy or other related and readable activitypub projects grow. But for now its been refreshing to be exposed to another type of network that is more or less absent in other social media networks.
