If you want to fine Catholic hospitals for following Catholic teaching, or prevent Jewish parents from circumcising their sons, or ban Chick-fil-A in Boston, then don’t tell religious people that you respect our freedoms. Say what you really think: that the exercise of our religion threatens all that’s good and decent, and that you’re going to use the levers of power to bend us to your will.
If you go to websites of the Left, or not a few atheist websites, you will see such swill in all its glory. Time and again, they will insist there is nothing wrong with any of these encroachments. Why? Because nobody is telling religious types they can't 'believe what they want.' No, they're telling religious types that they cannot practice what they believe.
But Douthat says it best. Let's be honest that liberalism is no such thing. It is simply a revolutionary world view that sees the traditional Western theistic tradition in the same way Western theists saw the Aztecs or cannibals of the Pacific islands. And thanks to the Supreme Court's spin on the First Amendment, a growing number of people believe that religion has a right to exist silently in a person's mind, but nowhere else in modern, secular, progressive society.
