I don't see how it is "nazi" to point out that the Poles are taking credit for the accomplishments of people they have driven out of their country. It is as if the Germans were to claim credit for Einstein.
Poland has had 10 Nobel Prize winners for science, an impressive number, but only one, Marie Curie, would be allowed to live in Poland today.
Perhaps, they don't realize the amount of resentment some Jews have towards Poland.
Einstein did develop as a person in Germany. I believe before the Nazis came to power, he was uninhibited in his career. His most famous articles were published in the begining of the century. Or are you counting Jews separately in every country? If you do so, then the question why there is "anti-semitism" has its answer right there.
And to your question why it is "nazi", you didn't ask that question when being pointed out how many Jewish Bolsheviks there were in Lenin's government.
