He does often use the phrase ‘cultural marxism’ though, and it seems closer to the bogeyman sense than a credible criticism of academia.
I did sociology in the early noughties, I agree marxism and post modernism were two big perspectives taught (sadly i’ve forgotten most I learnt) and we were encouraged to draw both for out essay, but we were taught how they both developed and the tensions between them.
Peterson rolls it all up into one thing, says post-modernism was basically just a rebranding of marxism, due to marxism being discredited by totalitarian regimes, and that it is all about the drive to power rather than the actual moral arguments. I don’t think that is right, either chronologically, or in representing their ideas (think marxism was still popular when postmodernists emerged, and there was considerable tension between the two, and I don’t think there were many theorists who made the switch). Then he says that it has taken over the universities, HR departments, media, and low levels of government.
To me that does seem quite bogeyman, that there has been a continuation of a totalitarian ideology, first known as marxism, now disguised as post-modernism, determined to gain power (rather than fairness) that will inevitably lead to totalitarian, and that worryingly they have already infiltrated all aspects of society, and it seems clear that he does this so he can raise the spectre of gulags and totalitarian government, to completely inappropriately dismiss arguments and movements he disagrees with (trans-activist have the same Philosophy as Mao etc.).
Can’t remember where I saw/read it, probably some youtube, but it was someone who made a good argument that what marxism and post-modernism do have in common is both are critical theories that demystify the world and undermine the supposed natural order of things. Peterson is the exact opposite, he is attempting to re-mystify the world, telling people that unfairness is the natural order of things, people aren’t oppressed, and rather than try and change the world it is all down to individuals to change themselves
