Oh, I guess I must have imagined the Roosevelt administration being stridently anti-Nazi from the beginning, and the mass protests whenever Nazis showed up in the US. Silly me.

You are correct that you are imagining this, because the US' relationship to Germany was definitely complex. Roosevelt was far from "stridently anti-Nazi" until Kristallnacht (1938 Nov 9), at which point Roosevelt recalled the US ambassador to Germany and allowed the 12,000 visiting Germans to remain in the US. However, despite allowing those Germans to stay, he did not push to increase immigration quotas.

Prior to Kristallnacht, the Roosevelt administration, Hollywood, petroleum companies, and much of the manufacturing base were very pro-Nazi Germany. The administration assisted Germany in circumventing boycotts while US petroleum companies provided fuel and oil despite European sanctions.
