They cut the whole section when O'Reilly was going on about the Xmas songs in school stuff - most of which has been shown to be inaccurate. Letterman didn't even know this, sensed it was bullshit, and changed the topic. You'd have a better idea of the tone of the program had the beginning been left in.

Now, the Yippie co-founder that just died early this week, Stew Albert, would have cleaned O'Reilly's clock in ANY debate. Stew had his head busted open by the cops at the Chicago Democratic convention police riot in 1968 - and was one of the main people that helped get rid of the draft in the United States. I didn't agree with much of Stew's politics, or everything he said and did in his life, by a longshot - but O'Reilly would be a sitting duck for a guy like him. No-Spine O'Reilly would rather pick on mothers whose sons lost their lives than a man who devoted his whole life to what he believed in, and had the scars to show for it.
