This is one of the most frustrating things about Peterson. He constantly speaks outside of his area of knowledge, often going against consensus and without substantively supporting his claims. It's natural for academics to dispute popular opinion, but you're going to have to actually put some leg-work in to prove your point. But if you make any criticism of weird or erroneous claims he can just argue that you misinterpreted him because his arguments are often vague and word salady enough so as to not have any concrete meaning (the most postmodern thing ever btw). His writing really sounds like an AI trying to mimic academic language.
Not sure how well received this will be here, but there's a really great article by Nathan Robinson on this topic. It's a bit long, but worth the read. It's where I found his weird
outsider art instructive figures. A bit I thought was esp spot-on was "People can have such angry arguments about Peterson, seeing him as everything from a fascist apologist to an Enlightenment liberal, because his vacuous words are a kind of Rorschach test onto which countless interpretations can be projected."
