Yes, mob justice and public humiliation are very useful when people do and think things you don't like. Just what we need to deeply heal our damaged society.
I understand why you have to exaggerate, though.
Certainly I join in your healthy fears of some misguided actions which have been attributed to "cancel culture". And I also concede that there have been quite a few such actions.
However, I'd also ask that you recognize that many of the reactions and consequences attributed to "cancel culture" have been entirely justified, and appropriate, and have resulted in overall good outcomes to society.
