I'm biased, though, because I find his lectures really difficult to follow. At least in the ones I've watched, he exhibits an oddly rambling style of speech that seems optimized more for some kind of narrative rhythm than for clearly conveying semantic content. He's very good at making it feel like every word is important, but then when I go back and try to figure out the actual statement being made it's like whole sentences just sort of fold in on themselves until nothing is left.
I don't think that's entirely true. The Peterson fan-groups on Reddit often have group readings of books that haven't been written by Peterson but have been recommended (Dostoevsky, Nietzsche, Solzhenitsyn).
I do agree that there's something of a cult of personality surrounding Peterson, and for that reason I try to keep that in mind and keep him at arm's length despite agreeing with a lot of what he says. But I do think that such behaviors are common and inevitable. Consider the "I f*cking love science" crowd and their focus on clips from Neil deGrasse Tyson or Carl Sagan (their written material is a distant second in popularity to their broadcast presentation) or the trend a few years ago of receiving news through a Stewart/Colbert-style format of ideology + humor. There's something almost inescapable about the human desire to associate with a group/club/tribe, to find a leader to rally around, and to indulge the urge to worship.
And I can't help but feel Peterson knows this. (His field alone should equip him with knowledge of these circumstances.) And it sometimes flashes through my mind that Edward Bernays has brought Freud to America all over again (which is not necessarily an indictment of Freud directly so much as how his techniques were put to use), and that Peterson, and others like him, know on one level exactly what they are doing. After all, evolution has primed us to jockey into position for the best possible access to mates, and power has always been intimately connected with that. (Which is another ways that Peterson reminds me on the 'Bernaysian Era', when the rich elite needed to guide the irrational masses but managed to conveniently ignore the applicability of those very same theories to themselves and their own motivations for operation.)
The enemy is all around you.
Access to secret "true" knowledge.
The world is corrupt.
A plan that if you follow correctly will lead to good things.
An enemy that alternates between specific and generalistic states.
Everything has to be framed through a set of ideological points at all times, which are reiterated in the otherwise minorist points of life.
That is not to say that he definitively is something of that kith or kin to that, necessarily. Just that I see several public figures these days that come out of one branch of science, platforming their knowledge of one field to the world of knowledge at large, and espousing thinking --- right down to phraseology, at times --- I have heard too often from sources these same individuals would claim to violently disagree with. Taking on Peterson's own postulations related to the co-evolution of the biological and memetic aspects of humanity (which in general I would agree with): I think the push to a what would otherwise be called a 'religious sensibility' can be --- and often is --- clothed in scientific language.
