When I lived in Manhattan and went to Columbia University, I heard many discussions in the Jewish community as to whether their allegiances should be with whites or non whites. At the time, it sounded like they generally thought their allegiances should be with non whites.
It was, after all, a couple of liberal jews who formed the NAACP early in the 20th century.
I think the first inkling that this might be a good idea came with the assassination of Meyer Kahane in the early 90s in New York.
maybe they should vote policy instead of skin color
