A lot of my friends have a problem with Peterson's beliefs, I have more problem with the lack of coherence in how he expresses things.
For instance Peterson says "you should be a Christian" but refuses to say if he's a Christian. I think we all should agree on the categorical imperative so if somebody is advocating that something is good for you but not good for them it suspicious. Like I have Christian friends who will tell me they personally have benefited a lot from their faith and I will tell you the same thing about Paganism.
Benzodiazepines can mess you up about as bad as Peterson says they have messed him up but his description of his symptoms (Tardive dyskinesia) is somewhere between incredible and fantastic, as is everything else he says these days. I think the saddest thing is that BZs impair learning and memory so that you don't learn to cope with life better with time the way most of us do. A friend of mine who has been taking them for 20 years still talks about the same subjects in the same way that he did back then whereas people who grow pick up new interests. SSRIs are a preferred choice for anxiety disorders because they seem to help people in the short-term with less suppression of long-term development.
I do think there's a need for a message similar to Peterson, that is, somebody who advocates for tradition and encourages young men who've been turned off from learning by a gynocentric educational system to seek knowledge -- but Peterson doesn't deliver what he promises. Neema Parvini does:

(Not to say I agree with Parvini about everything, like I'd have to pick Starhawk over Evola and I think second-wave feminism had something to say, no matter how hard it might be to live with, when it was countercultural in the 1970s -- but Parvini has a basic integrity which Peterson lacks.)
