Where I think this approach has been especially disastrous has been climate change. When people challenged the facts - which I don't entirely believe but the potential outcome is too serious to just blow off - they were humiliated and discredited, sometimes viciously. When people challenged the feasibility of solutions - ditto. Which in my mind signaled the worst - the desire to break resistance was stronger than the desire to persuade. Which led to a belief that maybe something more sinister was in the cards - a la Pol Pot's killing fields. Not a reasonable belief but when you see others dehumanized for questioning the know-it-alls, it's understandable.
