I'll make a serious post towards this thread, since Peterson fascinated me and I never really was able to express this. Also, this is probably what you expected to hear when you made this thread lmao.
I actually kind of appreciate Jordan Peterson, in the sense, that he does understand what it takes to turn yourself into a better person and doing purposeful things. I mean, it's probably expected when you've been a psychology professor for so long (at one point being an assistant professor at Harvard) and still do clinical trials. Of course, it's kind of "duh" when you listen to it. But, I'm probably stupid for not noticing the obvious sooner.
That said, I don't agree with his views on women nor some of his political views, but I don't think he's necessarily toxic. It's kind of true that when Peterson discusses theories and ideas that are not rooted completely in psychology, his arguments can fall apart. His knowledge on neuroscience is pretty outdated, commonly claiming that evolution, specifically lobsters, are a reflection of the modern day "dominance hierarchy" and to an extension natural selection. His cites the injection of serotonin into lobsters makes them a lot more confident, therefore, makes them more capable to perform as evidence. However, it's a kind of reckless jump to conclusion to fit his argument, because he lacks the knowledge of the neuroanatomy of both lobsters and humans, as well as concepts in modern neuroscience for this argument to hold up.
Another thing I think people misunderstand is Peterson's point towards political correctness. It's the fact that it's being forced as legislation. Now, he's being a dick to claim "I won't use a pronoun" and you have "to earn my respect to use a pronoun", but the bigger point is that it's legislation, which was the issue. It violates the basis of free speech to be "forced to speak a certain way" through government legislation, since I'm pretty sure a lot of people agree that being forced to say something should not be a power of the government. Of course, he makes the extreme argument that it could potentially lead to "Nazism", but he does have a point it is a slippery slope to have the government regulate what you say.
Also, Peterson's lectures makes it clear that his idea on "order" is influenced by other things besides Christianity such as Daoism and Buddhism. But, I think his ideas are just interesting for the most part. He has a lot of good ideas, but his other ideas can be incomplete or aren't sound with modern society (mostly at his view of women).
Anyways, with that out of the way, I did learn something from Peterson. This is more of a personal anecdote, but he sets these ideas in a way that are easy to understand, but complex enough for you to grasp the deeper meaning behind it. His idea on what built a meaningful life fully resonated with me, through the use of religious anecdotes was very helpful. Though, his view on a successful person is very western-oriented.
I suppose being the edgy teenager that I am, made me feel that life was inherently meaningless and that just gave me a fuck ton of anxiety, and looking through countless ways to try to help myself... I kind of fell into a rut. Though, I stumbled upon Jordan Peterson on "accident" (thanks YouTube algorithm), when I went on a YouTube binge.
He didn't really "transcend my understanding", like a lot of people who listen to him claim. But, he did re-adjust my worldview. He claimed that the meaning of life isn't to find happiness, which was pretty important, since whenever you feel unhappy it'll be associated with the thought "I'm failing at life." He brings a more religious point-of-view to it, which I've suppressed from my life.
The religious have always stated that "life is suffering" and I've never fully grasped the meaning of that statement. But, he made it clear to me why I've avoided that meaning towards life. It's hard to accept that life is suffering, because you would need to accept a lot of responsibilities in the face of that suffering. As an extension, it is responsibility that happens to bring some sort of meaning to life. Now, why didn't I understand this earlier? That's a mystery to me.
But, I'm certain this message is why people view him so positively. He emphasizes getting yourself together, and how to do that based on his observations and experiences as a psychologist, along with religious metaphors. He makes the point that way to improve the way you live is to bear your suffering and accept the shit that life throws at you. There will be a fair bit of pain along the way, but you become a reliable and respectable person if you can attempt to overcome all the things that life will do to try to fuck you over. I found applying these thoughts kind of helped me find more meaning in what I do. Of course, you should help others to alleviate suffering, you shouldn't be attempting to maximize it. But, it's quite funny how you feel the necessity to bear a load of some form to feel important.
This is my serious post for the year, and I bet this is a response you wanted to hear. This is my opinion of Peterson, which is probably what op was more interested in when making this thread.
