It's cultural Marxism. All the "Critical" theories -- race, legal, etc. -- come from 20th century neo-Marxists who realized the class struggle narrative wasn't working in the West so they had to come up with a different angle.
And what does Marxism do? It destroys. It tears down norms of all kinds. It eliminates the past. It's straight out of the Mao Cultural Revolution playbook.
And a lot of useful idiots out there don't understand that. They actually think it has anything to do with compassion when it doesn't at all.
