Americans’ religious faith greatly shapes their views of whether moral issues or practices are acceptable or not. In general, Jews and those with no religious preference are more liberal than Protestants, Catholics and Mormons in their views on various moral issues. These differences are most apparent on abortion and, to a lesser extent, doctor-assisted suicide and animal cloning. Catholics join with Jews and nonreligious Americans in saying gay-lesbian relations and out-of-wedlock births are morally OK.
