Yes I should have put an asterisk there for Foucault at least. I have had many fights with faux-left Foucault appreciators that use him to avoid, e.g. having an anti-imperialist stance. I was listing him just for the context: it is good to know his terms and ideas, despite his influence being negative and incorrect for practical organization, so that one can enter and participate in left discourse. I should have made that a category and added Trotsky to it.

Debord is a bit separated from them, though. His work is actually a quite gokd Marxist expansion on the analysis of capitalist society and it presents no distraction from the necessity of its removal.
