On Marx's "not a marxist"

[Carrol Cox]

There must be a number of people on this list who can cite the exact
text, which I can't, but I do remember its context, and it is a context
which robs the phrase of more than antiquarian interest. He was
referring to a specific small group of French communists who argued a
theory that was in fact anti-marxist but they labelled it Marxist.
Hence, if *that* is Marxism, then I'm not a marxist.
