I know that Poles were also getting killed and not just partying and I know that warsaw was blown up. But the germans put all the jews (not the poles) in a ghetto and then exterminated them. They didn't gas polish kids. You didn't find Poles escaping the Aryan side and trying to pass as Jews. Why would that be? and if the germans stopped at killing jews, christian poles would have been ok with that (except for a few good hearts) just like the ukrainians and the lithuanians.
This is because the Jews were viewed as the number one ideological and racial enemy of the German government and the German people. Poles were just a step down on the pecking order. Jews were killed because Nazi ideologues truly believed they, as a race, were the catalysts of all European disease, medical, political, and otherwise, and that they were a corrupting influence for all nations. Poles were killed because Germany wanted to expand its territory and rather than rule over foreign lands, as it had done in Silesia throughout the interwar period, it wished to kick what were seen as the occupying races out (Poles, Czechs, Russians, Lithuanians, and others) and repopulate said territories with ethnic Germans. Jews and Poles were killed on a large scale for different reasons, but neither group deserves more recognition than the other.
