In general, the United States has gradually become more tolerant of religious differences over time. According to U.S. News and World Report, the U.S. ranks among the top ten in religious freedom.
Religious intolerance in the U.S. has diminished. For example, the Know-Nothing party of the mid-nineteenth century was virulently anti-Catholic. At that time, many Americans were fearful of Catholic immigrants. In 1960, a Catholic, John F. Kennedy, won the presidency. More recently, Mitt Romney, a Mormon, won the Republican nomination for president on two separate occasions. A number of countries have banned the burqa, but the U.S. has not. In China, Muslims have recently been sent to reeducation camps. There is an undercurrent of hostility toward Muslims in America, though; this sentiment was caused by the events of 9/11. In general, however, the US is becoming more secular, so religious differences seem less important.
