Jews are shape-shifters. They can look like any human group, since a Jew is defined as "one who is born of a Jewish woman." Well, Jewish women can mate with gentile men of any race.
Unconverted, unbaptized Jews are, indeed, shape-shifters.
Regarding the Jewish notion that "a person can only be a Jew if they're born of a Jewish woman", it is false. The ontological, biological reality is that if a person's father is a Jew, but not the mother, that person still has as much Jewish blood as a person whose mother is Jewish but not the father. They both carry the genes, hence, they incur the same racial curse (Matthew 27:25), if they're not baptized and truly converted. They carry the same wickedness.
A full blown Jew will favor another Jew, who only gets his Jewish genes from the father's side, over any Gentile in business, legal or financial dealings. That proves they're schizo in regard to how they view their false notion of what defines a Jew.
