I can't speak for everyone of his adherents, but I don't think there is any evidence Peterson ever had any problems getting laid. He also wrote Maps of Meaning (in the late 90s early 00s?) which really should establish him as something more than some YouTube provacateur. I am most familiar with 12 Rules for Life and a lot of the criticism thrown his way always baffles me based on what I have read in that book. Telling men to grow up and take responsibility (and not specifically men but that is the demographic bias of his readership) seems the opposite of coddling young men driven to self-pity through lack of sex. Just my take. Still, I think the work of Jonathon Haidt is more profound and is my go-to (I know some have placed them in the same ballpark)
