Many people oppose "cancel culture" and "SJWs" because they see them as part of a vast leftist conspiracy imposing a political agenda across media, arts and academia and oppressing free (read: right-wing) speech at every turn. Many of the same people support Trump's abuses of power being wielded against those they consider "leftist agitators" like BLM and Antifa.

Both cases linked by fear of and opposition to the existential threat of "the left" as an insidious enemy within and a willingness to accept any means necessary to stop it.

I see both cancel culture and Trump's strange presidency as part of the same problem - the one that PG is talking about.

The rise of dogmatic orthodoxy and the inability to have a civilised dicussion where the participants disagree yet respect each other.
