From my piece in USA Today:

Well, “Americanness” is no less real than “Frenchness.” But in America, the logic of diversity has completely swamped any conception of Americanness as anything beyond platitudes about “inclusiveness.” Worse, Americans who think real inclusiveness requires learning English are told that their kind of inclusiveness is actually exclusionary. This merely exacerbates resentments because such policies are the only surefire way toward assimilation.
The point here is not to say that America has become “too Mexican.” Though it’s ironic that liberals who see nothing wrong with talking about America, the GOP, or various universities as being “too white,” “too Christian,” or not black or Hispanic enough should recoil in horror at such a thought. Rather it’s simply to note that such concerns are normal, human reactions to changes many Americans feel they were never consulted on. How could they be consulted when so much immigration is illegal? Americans are proud of being citizens of the most inclusive country in the world. But is it so outrageous for them to want it to be a bit more of a normal country, too?
