I'm sure if you ever become a star the whole American Polonia will go out of their way to claim you ;)
"If relativity is proved right the Germans will call me a German, the Swiss will call me a Swiss citizen, and the French will call me a great scientist. If relativity is proved wrong the French will call me a Swiss, the Swiss will call me a German and the Germans will call me a Jew."
It seems as though you're over looking the difference in the US between ethnic mixing and "racial" mixing.
Ah, you know yourself, some people think that "racial" mixing is the worst thing in the world.
In fact expect many people to post on here telling you how wrong it is.
For me personally and for the friends I have in Poland, it's a non-issue.
