I feel a satisfaction hearing that some figure on social media is embroiled in a controversy and realizing that I had muted them a long time ago. The common themes that turn me off to people in general is
Humor based on punching down, deriding easy targets in a way that implies a natural superiority over a superficially detestable outgroup
Huckster-like communication style, where grandiose, far-off promises are supported by conveniently unfalsifiable claims.
Tactical, endless derision of an enemy indiscriminately, even when the derogatory claims contradict
Self-aggrandizement or insults based on immutable traits
Lacking any ability to self-deprecate unless the self-deprecation is made obvious to lack any substance
This reminds me of that study at Google that found that the common predictor of the most successful groups who worked together on projects was a general sense of psychological safety among those in the group. In a group where people felt free to spoke their mind without potential severe social penalties, those in it came up with better ideas, and addressed issues more effectively.
