OK..lets use some reverse Psychology. Some Jews were not allowed in prior to WW2 for what reason again?
That was completely different and is now pushed by anti-Zionists for their twisted ends.
FDR could not allow that ship carrying Jews in because he was not popular in his 2nd term at that time and more importantly, it violated the 1924 Anti-Immigration Act.
Americans had had enough of mass immigration in the early 20th century and were massively unemployed in FDR’s 2nd term without any of the social safety nets that exist today. Turning away those Jews had nothing to do with the passengers being Jews.
