From the tenor of his article, it sounds like he has either joined the Paleocon Buchananite "pitchfork brigade", or has waded so deeply into valueless Libertarianism that he no longer sees Evil for what it is. Either way, he's off the reservation. My experience has been: scratch a Paleocon and you'll find an anti-Semite underneath. Scratch a Libertarian, and you'll find a coward.
Fightin' words, my FRiend.
