The great threat to religious faith in our time (more precisely, to the quality and meaning of faith) is populist nationalism. The democratization of the churches has led to that; but that is only a secondary consequence, inseparable from the democratization of entire societies. The primary element is simpler, and more important. It is that the religion of the nation, the sentimental symbols of the nation, are more powerful than religious faith, especially when they are commingled.
You would think that the pro-religion party would be more sensitive to substituting religious worship with worship of the flag.
Fortunately, there is a compromise position that doesn't turn America into a religion. The Republicans should propose putting a C-130 with a crew on 24 hour standby waiting to fly country music superstar Toby Keith to the sight of any flag-burning, so that he can kick the burner's ass back to France.
