It may be true that some people have been unfairly "canceled" in the sense of losing jobs or opportunities as a result of people's interpretations of their actions (see link for examples). But, to call this a "culture" is over-reaching. 1/2 https://www.theatlantic.com/ideas/archive/2020/06/stop-firing-innocent/613615/?utm_source=twitter&utm_medium=social&utm_campaign=share

"Culture" implies a common set of norms, beliefs, or practices shared by an identifiable community.

However, "canceling" has been practiced by disparate groups (communities), for disparate reasons (norms & beliefs) for generations. It's not a "left/right" thing, it's just human.

Coda: not all "canceling" is inappropriate. I'd like companies to "cancel" employees who actively engage violent crimes, for example. Or for platforms to (fairly) enforce a clear ToS (I will agree most ToS are unclear & we can debate whether or not enforcement is fair).
