William Saletan does not hold that position. He apologized for the series of columns he wrote, and acknowledged that he sourced them poorly. To argue that he agrees with you today requires you to argue that he wrote dishonestly. Were that the case, I'd have no reason to believe anything he wrote was in good faith. As it stands, the simplest explanation was: he was writing discursively, as an essayist; his ideas seemed good at the time; he was corrected; he changed his mind.

I also didn't call Saletan an idiot, obviously.
