Psychologically, the phenomenon is "data" rich and opens up so many dynamics to be observed and studied.  One reason it is a unique situation is that JP is a Jungian enamored clinician who is also a devoted trait researcher.  Already that combination sets him apart in the psychological community (In my experience, most psychologists do not sort into competence in both analytic thinking and traditional research methodology).  

But of course I like that because I am an analytic thinker who was also drawn to the 5 factor model.  The NEO-PI seems to be a gold-standard of psychological trait research.  The issues arise when we start calling the 5 factor model a personality inventory rather than a trait inventory.  Gregg articulates this in terms of the very real issue of confusing aggregate level analysis with individual analysis. 

So Peterson "gets it" in that he uses the analytic perspective for the tools needed to delve into the individual self, and the five-factor model for analysis of the aggregate trait level that the 5 traits reveal (OCEAN).  

So what remains are Peterson's own blindspots and less developed areas of self.  You can take a rough cut at it by observing that Peterson developed as a working-class white Canadian.  He thus appears to have insensitivities (relative to the humanities, not the lay population) to colonial dynamics along those lines, and those insensitivities draw to him a shadow audience of individuals that are conservative, ignorant, or regressive about race dynamics.  I think that the damage he will create, for whatever proportion of good, will revolve around his emboldening of race dismissal amongst groups and people who urgently should be receive education on the topic.  

I do not perceive Peterson as problematic in regards to gender.  Most of what Jordan Peterson says about gender dynamics is a toned down version of what I learned in undergraduate from women psychology professors.  

I do understand the Peterson hate, though, as I had similar initial reactions to him.  When his first video blipped onto my radar, I thought  "A white conservative just got flushed out like quarry to be taken down."  And the same primate part of me that anticipates a punch-drunk and wobbly fighter's knock-out in a boxing match was the same part of me that watched for Peterson to be torn apart by rational and irrational mobs of social justice warriors that smelled blood in the water and easy prey.  But it never happened.  He defeated every wave that came his way, and he's been doing it every day for over a year.

Also, to dismiss Peterson outright is to deny some of the very most powerful tools that emerged out of the field of psychology.  If the "left" rejects the baby with the Peterson bath-water, the right will continue to weaponize psychological insights and use them to manipulate a confused, agitated, and increasingly fragile populace.  There will be an increasing inability for individuals to determine what is bread and circus versus a substantive area to direct healing intellect and effort. 

Finally, I am privately aware of when the left uses psychological tools as manipulations.  My friends in politics call it "fighting dirty."  The ends, they believe, will justify the means.  I'm not so sure, especially when the left increasingly suggests a world where we are encountered only through our thin-sliced demographics.  The point, in theory, was that we would reclaim our histories in order that we could eventually transcend them.  If we get stuck in the trenches of the identities carved out by marketing teams, we will have at least shifted culture wars to a digital realm, 

but of course the fear is that we are on borrowed time to resolve the "brown-eye/blue-eye," "they/them" conundrum, because the ability to manifest global weaponry is exponential.  

So, in summary, the left will have to destroy itself in order to wage war on Peterson, and Peterson is entirely willing to sacrifice his life for his principles.  So better, I think, to cordon off the weak areas of his perspective and appreciate the benefits of what he is offering rather than alienate his faction as we plunge deeper into the battle for social memory (i.e., the culture wars).
