This isn't very related, but I'll bring it up because I just learned about it: The Xhosa cattle killings in South Africa: In the mid 1800's two children had a prophetic vision in which their ancestors told them that if the Xhosa killed all their cattle, their ancestors would rise from the dead, wash the white men into the sea and bring them new cattle. For reasons that are unclear, this was widely thought of as a good idea. So they killed all their cattle (over 300,000), leading to the starvation of about 80,000 Xhosa.
There are many stories in history that should teach us about the virtues of rationality, but this is an exceptionally direct one.

I do fear we're in a resurgence of ideologies kind of period. Where it becomes increasingly acceptable to believe irrational things. It's why I'm still very anxious about Trump getting re-elected. To have someone in that position in world politics that can go around... literally fighting windmills, seems so dangerous.

And it does tie in with having people like this talk show host, who when faced with someone saying "I don't want my country to facilitate a genocide," all they can do in response is divert and shout nonsense... and that's someone people apparently listen to, so this confused type of thinking resonates.
