I'm not sure HN is the forum for argumentation, but I agree that there is nothing in your post that merits downvoting. In fact, I think what you've drawn attention to is valuable. FWIW--from what I've come across--while I do sympathize with his frustration and distaste for, e.g., mindless campus activism, I'm not left with the impression that Peterson's views are particularly philosophically sophisticated. He seems to succumbs to polemical emotional outbursts in place of sober and cogent argument. These could be made more tolerable if he were able to offer some justification for the claims he makes. I know that Derrida addresses Marxism and its lingering "ghosts" (as much as Derrida can be said to address anything), but I do not quite understand how Peterson believes Marx is smuggled into the humanities (or wherever else) through "postmodernism". I don't know that you need to appeal to postmodernism to explain the presence of Marxism in the humanities. It was there long before postmodernism came about.
