Polish people commonly have blond hair and blue eyes. They look quite fair to Germans and/or Aryans in some regard. A whole bunch of other Slavs like Czechs and Slovaks, or Ukrainians, also tend to have some amount of blonde hair and blue eyes. How did this cope with the image of sub-humans?
Although I would say the same of Russians, they tended to be displayed as Mongolian-Asiatic hordes coming to conquer Europe. But they too have some amount of blondeness and blue eyes. How did the Germans cope with the image of Slavs with Aryan features?
