Is just Marxism with a much narrower and vague target. Plus, the arguments and writing are incredibly tedious. All culture is cultural appropriation. Their argument/tactic is to focus on uneven power dynamics, but guess what: power exists. Someone is going to exercise it. Therefore in whatever context, there will cultural appropriation by their definition. The real problem is they just want power for the progressive clique and we can all see where that would go if they ever achieve their aims - some mix of Soviet Russia, Venezuela today, and campus grievance committee meetings.
