I think that’s because the propaganda agencies, NPCs and censorship advocates haven’t arrived here in full force yet. When Twatter starts running their own nostr relay and cache, it shall be more customary here.
Let'em come on over. They're may not be as many as we think. And their message? I think they'll have to have a bunch of peer reviewed & supported pieces of information for all the narratives they want Nostrites to believe. Like the vaccine. Let's see the peer reviews supporting the idea they work. It's one community which is the exact opposite of what Liberal philosophy is all about which is separation of the people.
I worry that you're correct. For example, Minds is another censorship resistant social network, but there's almost no cordiality there between left and right.
