共和党白人至上论和纯种新教徒论一直是比较主流的,所以犹太人在那里会比较受排挤也不奇怪。具体我没有太多研究。
The Immigration Act of 1924, or Johnson–Reed Act, including the National Origins Act, and Asian Exclusion Act (Pub.L. 68-139, 43 Stat. 153, enacted May 26, 1924), was a United States federal law that limited the annual number of immigrants who could be admitted from any country to 2% of the number of people from that country who were already living in the United States in 1890, down from the 3% cap set by the Immigration Restriction Act of 1921, according to the Census of 1890. It superseded the 1921 Emergency Quota Act. The law was aimed at further restricting the Southern and Eastern Europeans, among them Jews who had migrated in large numbers since the 1890s to escape persecution in Poland and Russia, as well as prohibiting the immigration of Middle Easterners, East Asians, and Indians. According to the U.S. Department of State.homogeneity".[1] Congressional opposition was minimal.
Between 1900 and 1924, approximately 1.75 million Jews migrated to America, the bulk from Eastern Europe. Before 1900 American Jews had always amounted to less than 1% of America's total population, but by 1930 Jews formed about 3.5%. This increase, combined with the upward social mobility of some Jews, contributed to a resurgence of antisemitism. In the first half of the 20th century, in the USA, Jews were discriminated against in employment, access to residential and resort areas, membership in clubs and organizations, and in tightened quotas on Jewish enrolment and teaching positions in colleges and universities. The lynching of Leo Frank by a mob of prominent citizens in Marietta, Georgia in 1915 turned the spotlight on antisemitism in the United States.[117] The case was also used[by whom?] to build support for the renewal of the Ku Klux Klan which had been inactive since 1870.[118]
At the beginning of the 20th century, the Beilis Trial in Russia represented incidents of blood-libel in Europe. Christians[which?] used allegations of Jews killing Christians as a justification for the killing of Jews.
Antisemitism in America reached its peak during the interwar period. The pioneer automobile manufacturer Henry Ford propagated antisemitic ideas in his newspaper The Dearborn Independent (published by Ford from 1919 to 1927). The radio speeches of Father Coughlin in the late 1930s attacked Franklin D. Roosevelt's New Deal and promoted the notion of a Jewish financial conspiracy. Some prominent politicians shared such views: Louis T. McFadden, Chairman of the United States House Committee on Banking and Currency, blamed Jews for Roosevelt's decision to abandon the gold standard, and claimed that "in the United States today, the Gentiles have the slips of paper while the Jews have the lawful money".[119]
In the early 1940s the aviator Charles Lindbergh and many prominent Americans led The America First Committee in opposing any involvement in the war against Fascism. During his July 1936 visit to Germany, Lindbergh wrote letters saying that there was "more intelligent leadership in Germany than is generally recognized".
