Critique of post modernism

is there one good thing about Postmodern Neo-Marxism? It forces Marxists to define thoroughly classical Marxism in critique of post-modernism

The "good" thing is that it doesn’t exist. The person asking this question doesn’t have a clue it seems. First, no one calls themselves a “neo-Marxist”. That doesn’t exist. Secondly, postmodernism is incompatible with Marxism or socialist theory in general. Postmodernism is skeptical empiricist theory that attacks “structural” ideas such as the socialist theory of capitalism as a regime of class oppression and exploitation.

The person who wrote that Wiki page is the clown. Joan Robinson certainly never called herself a “neo-Marxist”. Moreover that Wiki page doesn’t actually substantiate its claim in any way whatsoever. And postmodernism is inheretnly inconsistent with Marxism since Marx was a realist in philosophy and his theory posits structures for explanation, “modes of production” with “social relations of production” as essential component. Postmodernism is opposed to structuralist theories of this sort.
