Peterson is inconsistent when he says that difference does not imply hierarchy or superiority. Differences tend to be related to inequalities. Now, someone may be the best cake baker in the world and the worst mathematician—everyone’s good at something.
He associates the 1960s with experimentation and development. He doesn’t consider the more Hitchens-sequel point that the 1960s were self-indulgent experiment and deviation. I suppose he confuses deviation, experimentation, & novelty.
