"Cancel culture" is a new term but not a new social action. Ostracizing someone is as old as man itself. Even animals practice it. But if a good friend or family member of yours was outed as an extreme racist or an active pedophile or something just as worse, would you want nothing more to do with them?

Friendship is not a matter of contract, nor do family ties imply enduring tolerance.

If you yourself were a Racist & Paedophile, then perhaps Not.
