zahavasdad: Not only are most Americans of mixed ancestry, and the focus in the US has always been on skin color rather than ethnicity, but most of the anti-Jewishness expressed in the US comes from persons of Jewish descent (who for the most part are militant secularists who hate all religious peoples). The handful of nativists aren’t taken seriously, probably since most Americans are non-WASP and most who are “WASP” have fairly diverse ancestors.
So if we are eventually forced to move, it won’t be Nazi style racial anti-semitism, but probably communist/socialist style secularism that will also be directed against others religious communities.
