Are neo-marxists not marxists? I talk with actual marxists and not a single one has used this terminology, so this really smells like something made up just so claims like the above can be made. It doesn't seem like a good-faith attempt to understand the positions of the "neo-Marxist professors." In my read of Jordan Peterson's stuff, there's a lot of that going on: claiming misconstrued context or playing semantic games to avoid the heart of the matter that his point of view is just not substantiated. The video is short, it's good to hear alternative opinions that challenge your own. Its good to hear alternative opinions that are well formed, even-keeled, and evidenced. To use an extreme example, I do not need to hear an opinion about how the Earth is flat or maybe white nationalism would be a good thing. Right of the bat, I'm told that these "neo-Marxist" professors are dangerous and encouraged to enter a moral panic about nihilism being taught to kids. That doesn't seem like its going to be a good and informative argument.
