No, cancelling is a bad thing. It represents a barabaric and ignorant Hobbesian paradigm of "justice" by the mob. The people who praise cancelling only do so out of ideological agreement with the dominant cancelling mobs and will be the first to cry if a mob of opposite ideological polarity did the same to them.

Anything legal should be allowed, this already excludes 95% of cancel targets. For the rare illegal 5%, only the courts and public authorities should be allowed to investigate and administer punishment.
