Nonsense. A lot of Jewish girls love waspy white guys (think Barbara Streisand and Robert Redford in "The Way we were"). Also, Jewish women are stereotyped to love black men. Moreover, Jewish men are known for liking "shiksas" (remember that Seinfeld episode when all the Jewish guys were infatuated with Elaine).
This whole rumor about Jews not dating "goyim" only applies to the ultra Orthodox Jews, which are a very small minority. The majority of North American Jews are secular liberals, and are known to date/marry outside of their religion.
