Most of the people I'm seeing get actually cancelled are... being considered "an enemy of the state working to overthrow the government".

I'm also seeing a lot of base-rate fallacy and availability bias issues (surprisingly, from many of the same people who complain about other people falling prey to the base rate fallacy w.r.t. Covid). That you can think of a few instances where people were loudly pilloried for, say, weaponizing the state use of force to racist ends, doesn't mean that it happens that often.
