I started reading this without realizing that it was political hack job. It didn't take long. "Cancel Culture" is a white supremacist meme designed to increase fear among the most insecure and bigoted. But, yes, your bigotry should never go unchallenged in public.
Ignorance and the desire to oppress are evil. If people who actively promote brutality and oppression are left fee to do their worst we all lose. And we have lost as we can see as the nation collapses from racist, and neofascist idiocy.
Change in cultures is achieved by redefining what is valid and what is unacceptable. The symbols of what the great majority can see as evil now or in the past should be removed. These are always symbols of oppression against people deemed different from the dominant elite.
We are actively redefining freedom as the well being of all and not the greedy desires for power of a tiny elite and their foolish minions. If being publicly challenged for your beliefs is too much for you than perhaps you should reconsider the source of those beliefs.
These attitudes need to be cancelled.
