I am not because I live in a pretty conservative area. So I try to get some leftist points through to coworkers without opening myself up to the ridicule of just being a “commy degenerate” in their eyes. So I think I can get through to them better without outting myself as a Marxist.
My Co-Worker gifted me a copy of a visual novel called "Marx for dummies" he found in the basement of the house he bought and I still can't decide whether that was out of respect and because he likes me or because he was dunking on me something fierce.
