the fediverse is the nickname given to [instances using] the pubg protocol

Haha I'm guessing that was meant to say ActivityPub

the original instances of lemmy all have a strong leftist bent

[Bonus info]

Reddit has a history of big events when a clump of subreddits get banned all at once when a newspaper reports on them. A lot of right-wing ones went to Voat and later *.win, and some socialist ones (notably /r/GenZedong) went to Lemmygrad, which became the largest federated instance at the time. /r/chapotraphouse also made their own fork, Hexbear, although while it was the largest, it wasn't federated with the rest for years. Most instances were either hard-left (e.g. Lemmygrad, Lemmy.ml, SLRPNK) or a slight left, but tge third most populous for a while was Wolfballs, a 'free speech' instance, de facto alt-right (US right-Libertarian style instance), which ended up defederated from almost all the others due to constant bigotry and rule breaking when posting on other instances. Wolfballs admin eventually shut it down before the Reddit API exodus because, among other reasons, they realized the neo-Nazis among their users were serious and not just trolling.

Overall, the few right-leaning instances are alienated from the bulk of federation and become islands or vaporize, but most just dismiss Lemmy or even the Fediverse at large as a left wing commie thing.
