Joe F: I've run into many Poles (as in Poles from Poland) in the US and while I will not generalize, in a couple of cases what started as friendly informative conversations devolved into statements which were posed as explanatary but in my opinion verged on justification, and those comments were just like yours of 21 Dec 09 - 08:01 PM.
You might be stating a common perception, but I challenge it as justification.
Poland had the same proportion of Jews to population before the War as the United States has African Americans to population, about 10%. After the War, the percentage was about 0.1% and the persecutions went on.
