Smug lefties

Reihan writes,

I grew up among smug lefties; and to this day, I know a disproportionately large number of smug lefties. I know a handful of smug right-wingers, but the vast majority of right-wingers I know, and I realize that this is almost certainly atypical, are thoughtful, open-minded, self-effacing, self-critical, and susceptible to evidence and persuasive argument. I mean, this is probably because I know, like, eight people who can be described as right-wing, nine if I count “knowing myself,” and several of the others are economists.

I'm in a similar situation, except the only right-wingers I know are Clinton-hating Neanderthals. I don't think I've ever met a "neo-liberal" in the flesh.
