Generally speaking, a young (20s) white male who weighs about a buck fifty soak and wet, has a shrill, squeaky girlie voice, and expouses liberal/progressive positions that his liberal professors taught him in college. When confronted with facts or opinions that are contrary to his beliefs, rather than presenting a cogent opposing point of view, he will call you names like "right-winger", "wingnut", fascist and of course his golden oldie "racist". He will accuse you of being brainwashed by Fox News, (or "Faux News" as he refers to it) and various other non-liberal media outlets that he despises. He has an unhealthy obsession with attractive conservative women such as Sarah Palin, Michelle Bachmann, and Christine O'Donnell and will spent an inordinate amount of time trying to convince you that these women are dumb and inexperienced.
When I told this New Castrati guy that man-made global warming was a hoax, he told me to stop watching Fake (Fox) News, got up and stormed out the door.
