I have a bit of a different prescription than you do: Instead of aiming to make the community saner, aim to make yourself saner, and especially in ways as de-correlated from the rest of the community. Which often means staying far away from community drama, talking with more people who think very differently than most in the community, following strings of logic in strange & un-intuitive directions, asking yourself whether claims are actually true when they’re made in proportion to how confident community members seem to be in such claims (people are most confident when they’re most wrong, for groupthink, tails come apart, and un-analyzed assumptions reasons), and learning a lot.

A kind of put on your own mask before others’ sort of approach.
