I think Rush is a doucher, but my problem isn't with him nearly as much as it is a problem with how people view him. He is a babbling, pissed off douche bag type of conservative, but there are plenty of those. My problem with him, and those like him (Coulter, Beck, ect...) is that people take them as a legitimate news source. As a corollary example, I enjoy Keith Olberman, but I know that his show is biased, ridiculous, and as entertaining as it may be to watch him bash the right during his show, I don't take his show as a decent source for political information. Back to the conservative side of this example, people like Limbaugh, Beck, and Coulter have all spoken at CPAC as welcomed faces of the conservatives.
sparknotes: he is an attention whore who says the things he does just to stir shit up, and he has every right to do so; however, he should be taken as the entertainer that he is, not a political source of wisdom.
