i’d be glad to.
Read about the immigration act of 1924. (Which while not based on communist affiliation per se, did heavily restrict immigrants from Eastern Europe)
Dont get to caught up on immigration legislation per se. Since my point was regarding the excuse. People were afraid of communists, Jews were occasionaly communists. Thus they were vary of Jews coming in. This isnt unreasonable. There is a nice wikipedia page on the First Red scare.
of course they were wrong!
Also dont just limit to communists read about the anarchist exclsuion act which became the immigration act of 1918. As you may have guessed many Jews were Anarchists (Emma Goldman comes to mind)
