Facebook is a terribly toxic place, and while Hive is far from perfect it has the big advantage of the Community structure. That means all the really weird stuff tends to end up in a few places and communities will tend to ignore things that aren't relevant to what they are about.
It also helps that we're all a bunch of individualists who will question what we see. Might not get it right all the time, but we don't take the lazy approach of relying on a group of paid "fact checkers" whose real job is to enforce the agenda the platform serves.
