I often agree with Bill Maher's larger points--years ago in Salon he wrote one of my favorite political essays, excoriating the South for not supporting presidential candidates from the rest of the country, and telling them, essentially, to get the fuck over the Confederacy--but I think he's reflexively self-congratulatory, lacking in introspection, and seemingly, a bit of a douche. (Does anyone else remember when he mocked developmentally disabled kids on a segment of "Politically Incorrect"?)

Still, his new piece for Rolling Stone, "Dickheads of the Year: My Picks for the Biggest Assholes of 2007", should be added to school curriculums nationwide:
