> Last month, a hyped debate between psychology professor Peterson and philosopher Slavoj Žižek had the former spending his opening remarks stumbling around Marxism, having only just read The Communist Manifesto for the first time since high school. As Andray Domise wrote in Maclean’s, “The good professor hadn’t done his homework.”

This is a little bit harsh on Peterson because a lot of Marxists themselves haven't read Marx. You could say that the intellectual history of marxism (at least in the second half of the 20th century) is comprised of a large majority of "marxists" who haven't read his works and a small minority who have done so and who at least have a general idea of what marxism really is about (if it matters I do believe that Žižek has indeed read Marx and he knows what he's talking about).
