I don't know about his views on psychology, but his historical (and political) perspectives are garbage.
Isn't he pretty much just a standard Canadian left-liberal who is critical of certain elements of contemporary "woke" ideology like with the trans stuff like Joe Rogan. All these college students calling him alt right or even a nazi because he disagrees with them on like two or three things strikes me as pretty hysterical.
Regardless I'm not a fan because he comes off like a pseudointellectual sophist most times I've seen him.
He really isn't a "standard Canadian left-liberal." I don't think he's alt-right, and not a Nazi. But he does not describe himself as a left-liberal, rather using that overused "classical liberal" label. He really has nothing to do with mainstream "Canadian liberalism" and spends his time associating with right wing characters like the aforementioned Maxime Bernier and various anti-vaxxers these days.
