Knaves, Fools, and Quantitative Easing - NYTimes.com:
"When the going gets tough, the people losing the argument start whining about civility. I often find myself attacked as someone who believes that anyone with a different opinion is a fool or a knave; as I’ve tried to explain, however, that’s mainly selection bias. I don’t spend much time on areas where reasonable people can disagree, because there are so many important issues where one side really is completely unreasonable."
