I totally think we could come up with a definition...
Being booted off Twitter is not cancel culture
Having people not buy your albums is not cancel culture, however, being threatened is.
Not having a contract renewed because a company thinks it’ll lose money is not cancel culture.
Preventing people from seeing someone speak (non-hate speech) in public, or disrupting the speaker who has a right to speak and be heard is cancel culture.
Accusing Petersen, Sam Harris, Rowling or that pompous bag-o-crap Ben Shapiro of hate speech and trying to prevent them from speaking is cancel culture.
Can we start there? Do you agree with my list?
