I think by very nature of the Fediverse having somewhat leftist ideas baked into the design philosophy (decentralized, transparent, FOSS, and communal in design), that it gives the Fediverse an intrinsically left-leaning audience, so it may be harder to find a right-leaning community that isn't extreme right like some others have mentioned. In general, I'd say that the needle points significantly left-of-center on the Fediverse as a result.
With Threads possibly federating soon, it's possible that that may attract more conservative users to the Fediverse as a whole, which may foster the development of more conservative corners of the platform for those who want to venture outside of Meta's bounds. Though that mostly applies to the Mastodon/microblogging side of things, not so much the Lemmy/Kbin stuff. Though technically Mastodon and Lemmy are compatible, as well, so that may still bring more conservative spaces, as well. Time will tell on that.
