Polish Americans score one of the highest in IQ tests.
Of course since you hate Polish Americans you will just say IQ isnt enough.
Given that IQ tests have been thoroughly discredited, it really isn't enough.
Still, statistics please? I'm not interested in PolskiMoc style "facts" - we need evidence!
Now, those Scottish-Americans who wear their kilts to the mall and talk about how Scottish they are (even though their ancestors came to the new world hundreds of years ago) are the ones you should be critiquing more. Same with Italian-Americans (most are mutts) who try to mimic real Italians and have Italian tattoos, bumper stickers, window flags etc.
They sound equally idiotic. I can imagine that if I encountered such idiots, I'd laugh in their face. I do know the kind though - they learn Gaelic despite having ancestors who came from a non-Gaelic area. Morons.
However, this is PolishForums, and so, off topic.
