Some of America's smartest academics work at the Hoover Institute (associated with Stanford U.) instead of directly at a university because of academic politics shouting down any kind of balanced or data-driven analysis.

Just delete twitter, than you do not have to read this garbage. Same for other social media.

This is about somebody's career being seriously affected by something they wrote that at any other time would have been a fairly reasonable opinion to hold.

Sure, Uhlig didn't have to read that stuff on Twitter. How would that have saved his editorship of the journal? Twitter feuds have real-life consequences.

Hm, the actual tweets are claiming that the BLM movement has been taken over by flat earthers and creationists and continues by calling protestors irresponsible children.

"Cancel culture" is an alt right dogwhistle as far as I'm concerned, but the notion that you will not/should not get internet-yelled-at if you publicly post dumb, paternalistic stuff on twitter I can't quite bite on.
