I haven't used Mastodon much, but in my experience, the Fediverse is mostly being created by people who are politically left (socialists, anti-capitalists in general), so the content I've seen leans that way and they mostly take a hard stance on hate speech. Check out dev.lemmy.ml (federated reddit) for an example of what I mean. However, anyone can create an instance in the Fediverse, like when Gab created their own Mastodon instance. Basically every other instance chose not to federate with them, though. That's what is nice about the Fediverse, you can pick what community with what rules is best for you.
