I don't know about the others (I don't watch Fox very often because their bias is so blatant, my bullshit meter pegs out almost immediately), but Bill O'Reilly operates entirely on a mix of testosterone, adrenalin, and bile. Two modes: loud and obnoxious, and even louder and more obnoxious.

And Geraldo Rivera is all ego and no ethics.

People actually watch this bellowing fest thinking that it's news?
