did anyone actually clarify the difference between a jewish pole and a polish jew?
All individiuals in any given nation have a national "citizenship", "ethnicity", and "religion". In a unique case, most individuals who follow the Jewish faith consider their religion an ethnic group as well.
In the USA for examle, all legal residents are considered "Americans". Then, for each American, it can be broken down into: Italian American, Polish American, Jewish American, etc. The same goes for Poland. All legal resident of Poland are "Polish". Then you have German Pole, Catholic Pole, Jewish Pole, Lutheran Pole, Musliim Pole. Not complicated at all.
That said, Solomon Morel is a Jewish Pole or Pole of Jewish descent. I have a friend whose father is a Russian of the Russian Orthodox religion, and his mother is a Catholic Pole. He lives in Bialystok. When asked his nationality, he states: I am a Catholic-Orthodox-Russian-Pole. Konstanty Gerbert and Adam Michnik for example are Jewish Poles. Where I live, the region has numerous Gypsy Poles. And what about the recent Brazilian football player that got Polish citizenship? Well, he is simply a Brazilian Pole, or a Pole of Brazilian descent. Of course, he might also state it like this: "I am a Polish citizen of Brazilian descent", if he wishes to reflect the fact that his roots aren't ethnically from the region where Poland is geographically located. To break it down further, Polish belongs to the Slavic category, just like Germans belong to the Germanic and Swedes to the Nordic. Simple, right?
A "Jewish Pole" or "Polish Jew", IMO, the same, meaning: a Polish citizen with Jewish roots, or a person with mixed ethnic Polish slavic and Jewish roots.
