Muslims purposely target Jews on campus with insults and many other ways of making them feel no wanted.
Sephardim picked this up technique of subtle harassment from Muslims. They do it to Ashkenazim pretty consistently. But then you have some Sephardim that are appalled at this behavior, but they can't do anything about it. There is always at least one that makes life intolerable for the Ashkenazi until he is forced to leave town. [Unless the area is Ashkenazi and the sephardim are the guests.]
