Disclaimer: I haven't taken in a lot of JP's writing or podcasts so this assessment is mostly from osmosis
1) Peterson understands that a growing problem in the West, as it becomes more secular, is the lack of meaning in life (Peterson purports to be a Christian but is cagey if pushed on the exact extent and nature of his belief: e.g., on the question does God exist, he replied "No, but I’m afraid he probably exists")
2) For some reason his message resonates with men far more than women. Perhaps it's because of the many men living under ground by the glow of their video games. Someone needs to tell them to get up and make their beds, and that simple act may lead to an incipient feeling of agency which is a stepping stone on the way to meaning
3) To the extent he pulls neck-beard gamers out of their basements and into the world, he is being a force for good. If his message doesn't resonate with you, well, no big deal, right?
4) Since his severe illness and (so it seems) near-death, he does seem more humble and less antagonistic towards his ideological and intellectual rivals, though has not really retreated from his position otherwise (see
this for example)
5) For anyone who's at all accustomed to his speaking style,
this parody nails some of his more absurd qualities; the real JP can occasionally talk himself into ridiculous contortions
On balance, I'm far from captivated by him but I do believe he has a reasonable diagnosis of a couple of the pathologies in society. Weird how polarizing he can be, though, judging by this thread. Maybe someone can post some lobster memes to turn down the temperature.
