I've noticed that after four years, my number one page in terms of hits is still the one asking when did Bill Maher become such an asshole? Apparently he really pisses people off. Although I can't speak for the masses, I can tell you why he pisses me off. It's not just that he's gotten much less funny and much more bitter over the years. It's not that much of the time he's just flat-out wrong with the "facts" he spews. It's that when he does shoot his mouth off, most of the time without any kind of support, he's so damn smug about it. And since he's usually doing it in a monologue, there really isn't anyone there to challenge him. So he has all the righteous condescension of the gold medalist in a one-person race. But hey, I support his First Amendment right to lie his ass off, but I also support my First Amendment right to call him a giant douchenozzle.
Anyway, here's a couple of other people taking him to task, and doing it much more eloquently than I.
