Threading through the history of the United States is a long line of reviled newcomers. In the 1850s, Irish and German Catholics were vilified by the Know Nothing movement. In the 1890s, Italians were subjected to frequent lynchings. Jews of the 1930s were excoriated by Father Charles Coughlin, Henry Ford, Charles Lindbergh, and the Ku Klux Klan. In the years following September 11, America’s 2.6 million Muslims have often found themselves facing similar kinds of hostility.
