At the risk of sounding like Paul Krugman — who returns to a handful of cherished topics over and over again in his New York Times column — I want to revisit one of my hobby horses, which I most recently raised in my discussion of Hobby Lobby.
My own cherished topic is this: Liberalism’s decline from a political philosophy of pluralism into a rigidly intolerant dogma.
The decline is especially pronounced on a range of issues wrapped up with religion and sex. For a time, electoral self-interest kept these intolerant tendencies in check, since the strongly liberal position on social issues was clearly a minority view. But the cultural shift during the Obama years that has led a majority of Americans to support gay marriage seems to have opened the floodgates to an ugly triumphalism on the left.
The result is a dogmatic form of liberalism that threatens to poison American civic life for the foreseeable future. Conservative Reihan Salam describes it, only somewhat hyperbolically, as a form of “weaponized secularism.”
The rise of dogmatic liberalism is the American left-wing expression of the broader trend that Mark Lilla identified in a recent blockbuster essay for The New Republic. The reigning dogma of our time, according to Lilla, is libertarianism — by which he means far more than the anti-tax, anti-regulation ideology that Americans identify with the post-Reagan Republican Party, and that the rest of the world calls “neoliberalism.”
