Jordan Peterson's logic only works in a bubble where he leaves out all the relevant information that doesn't support his positions - which all come directly out of his emotions and not out of any sort of masterful cognition. He essentially builds intellectual sounding frameworks to support his hurt feelings, and that appeals to a lot of guys with the same hurt feelings.

Glad your friend found his way out. I hope that more people will have that same kind of epiphany in the next year.
