U.S. has Italian-Americans, Irish-Americans, German-Americans, Chinese-Americans, Indian-Americans, Mexican-Americans, Jewish-Americans and so forth. It all works.
Are you from US? If so, look around first how it works.
What's the big problem then about being a Polish Jew?
No problem!!! Being Polish Jew is like being member of ruling class in Poland, khmm, not Poland exactly, because Poland is dead. It is wonderful to be Jew in Polestina aka Judeopolonia, now. You may be untalented, ugly girl like Anna Mucha or Magdalena Schejbal but you will be media starlet just because you are Jewish. You may be untalented, stupid man, but you will be "high level professional specialist" in any branch, because you are Jewish. There are abt. 500-700.000 Jews in Polestina, all in main positions in state structures and in business. In last years, there are abt. 100.000 new Jews in Polestina, mainly from US and Israel, because of "rapid way" for Polish passport, established by former president Kwaśniewski, when Jew can get Polish passport during 3 weeks (as to the true Pole from - for example - Kazahstan or Russia, it may be 3 years to obtain Polish passport).
Polestina is third Israel now, Polsrael, after Israel and USrael...
So, I see now, that this forum should be probably rightly named PolJewishForums.com....
