History is written by the winners, if Cancel Culture "wins" this will just be seen as a positive embyrotic formation of the dominant culture eradicating and stomping out evil in the world via a superior tactical formation (cancellation). If they win this will be seen as a very primitive form of mob-cancellation whereas in the future it will be cancellation via sophisticated "fair" social-credit scores.

If the anti-cancel culture people win out culturally this will be seen as a historic dark age of self-censorship and a period of significantly degraded cultural expression.

All history is relative.
