"Cancel culture" is orthogonal to the issues you're describing, I think. Professional and social life is very unfair for people across many spectra of belief and being, sadly. I'd argue there's been growing outrage about both sorts of phenomena in the past few decades.

If some sort of culture deems you impure, you're likely to be outcast. Different people just happen to run up against different cultures.

Discrimination based on immutable attributes is inherently much more unfair, but unfairness is still a battle waged on many fronts.
