Jordan Peterson on egalitarianism vs. biological essentialism

The whole idea that people are a blank slate and that everyone's equal at birth and that everything that makes people different is a consequence of socialization - that bloody idea has been dead among anybody who is reasonably educated as a scientist - it's been dead, I would say since the mid '60s.  Dead!  No one even talks about it.  But among these postmodernist types, man, they don't give a damn for facts.  In fact, facts for them are merely whatever the current power hierarchy uses to justify their acquisition of power.
