Being "wrong" equals being "serious" so that in the Village, you are "always right".
Thus, a conservative moron that wants to bomb everybody preemptively gets to go on TV after being wrong consistently about everything for more than a decade.
I'm not the world's biggest Noam Chomsky fan, but he's never on TV. Ever. Maybe C-Span once a decade.
There's no actual "leftist" on TV -- Olbermann & Maddow are just "leftist" by comparison. The last real "Leftist" on television was the "Mao Tse Tung Hour" and that was in a movie.
Come to think of it, that was the last actual left-wing violence too, and like "B-Girl" it was a fabrication.
