Affiliate Marketing Secrets

Most white supremacist groups, in America at least, affiliate themselves with Protestant Christianity. How then, could they claim to hate Jews when it has been historically proven that Jesus himself was a Jew/Semitic? Is there justification for this monstrous hypocrisy?
Jesus was born a Jew and died a Jew. He was born to a Jewish mother in a Jewish community and was circumcised eight days after his birth, as prescribed in Jewish law.
Mary was a Jew, and any jew can and will tell you that if the mother is jewish all her offspring will be jews as well.
