Nostr as a protocol is early but it appears to be mainly normies ironically enough.

Like one Nazi, & a fee wokes.

Mainly I'd say Nostr is independents, or Libertarians, no Neocons, or NeoLiberals, or really any major political activity.

You can generally tell the politics of a social media by scrolling for five minutes but so far on Nostr no one has dominated yet.
