Jonah Goldberg takes down that awful phrase so beloved by the progressive left: "You're on the wrong side of history."

(On) the home front, liberals insist that opponents of same-sex marriage should give up now because they are sure to lose eventually. And on the international stage, when Barack Obama castigates Vladimir Putin for being on the wrong side of history, what he's really saying is, "Don't worry, we don't need to do anything, History and her long moral arc will do the heavy lifting for us." No wonder the British historian Robert Conquest complained that the phrase has a "Marxist twang."

One irony is that although a slogan that glorifies history, it is a statement about the future, not the past. That's because history is full of episodes that would, with a moment's retrospection, illuminate the vacuity of the phrase.
