Marxist
adj. common term used to describe someone who does not believe what you believe. Note: most abusers of this never read anything by Karl Marx (save maybe his propoganda script) so they generally have no idea what he is all about.
Example:
I am tired of that Marxist never agreeing with me. I mean, i am Glenn Beck, and i never went to school, but all my ideas are grand and spectactular.
