Who's subverting Marxism?
If you're talking about someone like Foucault, his concern was to subvert dogma. He got sick of people asking him about Marx, as if his work was defined by whether he was for or against Marx.
One of the most dedicated upholders of Marxism as a grand utopian narrative is "postmodernist" Frederic Jameson. In his big book on postmodernism he sums up his project as a retrieval of the sixties call to "name the system" in order to change it.
I really don't know what people are on about with the idea social constructionists/pomos/etc. are "subverting Marxism."
