I had no idea...
Speaking as someone from England, I didn't realise there had ever been an anti-semitic feeling in America. Have things changed in the last sixty years or am I just spectacularly misinformed?
I was thinking that a lot of the Jews in America at that time would have been refugees from Europe so this might be more of an anti-immigrant thing and that the Jewish community were just a scapegoat.
Could somebody fill me in on this period of history?
