The reason why you gentiles hate Judaism is that you yourselves have no mechanism to sustain your own existence when faced with extreme adversity. Judaism keeps the Jewish people in existence even under thousands of years of exile and oppression by systematically protecting and nurturing Jewishness itself. When foreigners flood your country you will be assimilated and thus destroyed (non-violently but destroyed nonetheless.) Jews however will be fine no matter how much immigration occurs because Jewish religion prevents the erasure of Jewishness by assimilation. You gentiles don’t have this because you are not the eternal nation. Babylon and Rome have fall but Judea never falls.
