@thomasfuchs I think power dynamics are still at the root....
Lots of folks who find their own tiny power by following / supporting / being in (what they perceive as) the "in-group" of an influential politician or mogul who is one of, or is funded by, these billionaires. They see being able to remain in that group, and feel that tiny bit of power, as attached to the claims and beliefs that they now hold.
And when those beliefs start being challenged, they lash out defensively.
My best guess.
