Full quote: "Jews often engage in a form of biological mimicry. In order to infiltrate a host population and conceal their identities while remaining Jews, they have their daughters marry male members of the host population. The offspring are Jews since the mother is a Jew (a Jew is someone with a Jewish mother). However, the offspring have the name, manners, appearance, and sometimes the religion of the father thus enabling them to advance as Jews within the host population while remaining less obvious as Jews. Sometimes Jews convert to the religion of the majority out of convenience or necessity. Such was the case with the Marranos of Spain and the Donmeh within the Ottoman Empire."
