Everybody basically hated Jews in the 1930's, the USA included.
Anti Semitism was somewhat more common then in the USA then it is now but it was by no means a mainstream theme. You must be mistaking the Klan for mainstream American sentiment which is how bigots operate.
[They aren't so innocent.
The NKVD was dominantly you know who.
I have no idea what you mean.
Father Coughlin was popular.
Anti-Semitic quotas were also common in the United States.
History of antisemitism in the United States - Wikipedia
In the first half of the 20th century, Jews were discriminated against in employment, access to residential and resort areas, membership in clubs and organizations, and in tightened
quotas on Jewish enrollment and teaching positions in colleges and universities. Restaurants, hotels and other establishments that barred Jews from entry were called "restricted".

In 1922, educational discrimination became a national issue when Harvard announced it was considering a quota system for Jewish students. Although it was eventually dropped, the quota was enforced in many colleges. As late as 1945 Dartmouth College had a limiting quota of Jewish students. To limit the growing number of Jewish students, a number of private liberal arts universities and medical and dental schools instituted a quota system referred to as
Numerus clausus. These included
Harvard University,
Columbia University,
Cornell University, and
Boston University.[

Yale University, which already had such admissions preferences as "character", "solidity", and "physical characteristics" added a program of
legacy preference admission spots for children of Yale alumni, in an explicit attempt to put the brakes on the rising percentage of Jews in the student body. This was soon copied by other Ivy League and other schools,[

Jews encountered resistance when they tried to move into white-collar and professional positions. Banking, insurance, public utilities, medical schools, hospitals, large law firms and faculty positions, restricted the entrance of Jews. This era of "polite" Judeophobia through social discrimination, underwent an ideological escalation in the 1930s.
Restriction on immigration[edit]
In 1924, Congress passed the
Johnson–Reed Act severely restricting immigration. Although the act did not specifically target Jews, the effect of the legislation was that 86% of the 165,000 permitted entries were from Northern European countries, with Germany, Britain, and Ireland having the highest quotas. The act effectively diminished the flow of Jewish immigrants from Eastern Europe to a trickle.
