That's a very Libertarian view, robomatic. Everyone has it wrong.

Right now we're in a period of heightened political correctness that puts some previous episodes to shame. Opinions expressed publicly that don't completely align with thought leaders are to be shamed and that person driven out of their job and out of existence. Despite this practice, the term "cancel culture" has been adopted by several political groups and is therefore meaningless.

This is a drastic case of what Derrida described as the margins writing back to the center. Colonized voices are speaking back to the colonizers. Non-mainstream groups are lecturing the mainstream for being blind and obtuse. White populations are fish being asked to see the water they swim in (and to share it).

It's a difficult process and there is overkill, but it needs to happen. I've heard authors interviewed on my local NPR station who discuss the problems of shaming and cancel culture; I meant to pick up one of the books mentioned but have lost track of that note to myself.

Political correctness is an issue for White people who are trying to position themselves alongside Black Lives Matter in a way that isn't tone deaf to the issues at hand. In the process we're all throwing stones at each other's glass houses, so people are bound to get hurt.
