In a speech in October 1924, Coolidge stressed tolerance of differences as an American value and thanked immigrants for their contributions to U.S. society, saying that they have "contributed much to making our country what it is." He stated that although the diversity of peoples was a detrimental source of conflict and tension in Europe, it was peculiar for the United States that it was a "harmonious" benefit for the country. Coolidge further stated the United States should assist and help immigrants who come to the country and urged immigrants to reject "race hatreds" and "prejudices".
