Jews are religio-nation, Torah is what defines Jewishness and according to the Torah, a Jew is not necessarily he who was born to a Jewish mother but also one who sincerely converted through valid Torah Judaism conversion (Orthodox, though some "Orthodox" Rabbis use their titles in order to destroy Torah Judaism, among them "Rabbis" who help hundreds of thousands of Gentiles to mark V under the Jewishness clause by organizing mass "conversions, and thus are worse than both Hitler and Paraoh) - a Ger Tzedek.
The only ones who considered Judaism a race were the Nazis.
