Is the BLM movement looking to overthrow corporations and provide them to the people right now? If so that's a Marxist movement, but I have not seen any of that. Marxist ideas are held within environmentalists as we need a Marxist approach to natural resource management so I don't think Marxism is a bad move for some things... but BLM as it stands right now is not a Marxist movement and the people who name call it Marxist to bring it down, don't know what they're talking about. I'm sure you've seen the racists terming it Marxism as an attempt to use cold war rhetoric to bring it down?
