Salon presents this essay as an example of conservative apostasy, which I suppose conservatives are supposed to read as some kind of deep criticism.
But this guy is no conservative apostate. He's just a recovering jackass. If you read the whole thing, you see that Mr. Big Time Conservative here really just had a brief--three or four years or so--flirtation with right-wing political activism before reverting to the left-of-center fellow he was before 9/11. Furthermore, this dalliance with political goofiness mostly occurred during--surprise!!--his college years. Big deal. And shame on Andrew Sullivan for treating this navel-gazing tripe as some kind of deep, introspective thought.
