I've always found the latter term irritating as all get out. It's a smug, superior attitude expression that implies people of faith can't reason or think logically. It also is an explicit claim that atheists are inherently logical and rational thinkers. This, too, does not necessarily reflect reality. There are indeed rational, thoughtful atheists of the George Will variety. But there are also a lot of smug boneheads in the vein of Janeane Garofolo and Bill Maher under that umbrella, too. In my own personal experience, I've encountered far more of the latter than the former.
George Will? Learned something new today.
