"Immigrants make America great."

There are two certainties in American political life: immigrants enriching America's social mosaic and nativists saying immigrants are a threat to the American way of life.  In the 19th century Protestant nativists said Catholics loyal to a foreign pope could not be loyal to the United States and they, especially the Irish, would bring, "Rum, Romanism, and Rebellion."  The nativists of today are just as wrong as those of a century and a half ago.
