Consider a lot of what gets classified as cancel culture is:
1. Boycotts - OK we should be forced to purchase things (like Goya, or ads on Tucker Carlson's show) that don't share our values? No, that's crazy...
2. Organizational politics - The Pinker thing[1], and the issue with the Poetry society, has more to do with the internals of some organization. Should we restrict those advocating for changes to organizations they belong to?
3. Firing - Either organizations are able to have 'speech' or they're not... And without cultural norms, we're not going to from on high create top-down standards around which values are 'correct' or not.
I have yet to see a PoV neutral definition of 'cancel culture' that doesn't devolve to litigating whether the issues for the canceling are legit or not.
