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.
It might be where I live but almost all chuds I've met barely know what a communist is, much less declared us to be their mortal enemies. My experience has been more like being treated like a conspiracy theorist goofball who worries too much rather than some kind of outright hatred. I'm completely willing to say this might be some kind of white, masculine privelege I have.
