There are a large number of people who spend a good majority of their time and energy worrying about something called "postmodern neo-marxists", while rather amazingly, not being able to name a single one, or describe what they believe. Apparently though, these mysterious postmodernists think that "everything is as true as everything else" (a position that no one has ever held), and are engaged in some kind of systematic plot to destroy Western Civilization, by using...linguistic relativism, or something? It's kind of hard to say.
