I've come to believe that Bill O'Reilly is unstable, and along with people like Ann Coulter and Michael Savage, sets a tone for discourse in this country that is downright dangerous. People should not support this guy by buying his books or watching his programs. Free market response to hate speech.
From Media Matters for America : "Fox News host Bill O'Reilly said that Los Angeles Times editorial board wouldn't understand his objection to legal representation for detainees at Guantànamo Bay, Cuba, until terrorists "grab [editorial page editor] Michael Kinsley out of his little house and they cut off his head." He further opined: "And maybe when the blade sinks in, he'll go, 'Perhaps O'Reilly was right.'"
