While there's truth to it, especially that racist American laws were inspiring to Hitler, it's important to remember that fascism and the Nazis were never widely supported in America.
Polls from the time showed that while a large majority of Americans supported isolationism and wanted to stay out of the European war in the 30s, they generally disapproved of Nazism and Hitler.
>As early as March 1935, nearly half (43%) of Americans polled were supporting boycotting the Berlin Olympics as a protest against the Nazis.
>November 1938 Gallup poll found that 94% of Americans disapproved of the Nazi treatment of Jews in Germany.
So the reluctance of the US to enter the war was rooted in isolationism and the trauma of WWI, not support for Hitler. Sentiment against Hitler and Nazism was widespread throughout the 1930s.
