I’d recommend reading Ross Douthat as a matter of routine just because he’s a sharp writer. This post on liberalism and pluralism is no exception:
But this is where the problem comes in. Because as Bazelon’s blithe (and increasingly typical) dismissal of current religious-liberty concerns suggests, it’s precisely when people in liberal societies see themselves as out on the vanguard of history that they’re least likely to concede that they might, just might, be making a mistake, and most inclined to feel instead that the thing to do is shatter the shield wall around the remaining bastions of unenlightenment rather than permit them to persist. It’s when a consensus is at its most self-confident, in other words — and therefore most vulnerable to the errors of overconfidence — that the kind of pluralism that might serve as a corrective becomes hardest for that consensus’s exponents to accept.
