In a weird kind of way I actually respect Pat Buchanan because unlike most racists he articulates pretty well and honestly just what his racism is all about. Obviously that doesn't, you know, forgive the racism or anything but it's oddly refreshing. By honest I don't mean that he's "correct," just that he doesn't try to disguise his reasons, whatever their basis.
What isn't refreshing is his apparent immunity from peer criticism or career consequences for his racism.
