I hope that I am posting this in the right place, but something has always puzzled me about Nazi treatment of the Jews. For the sake of this question leave aside the whole wider issue that you can't treat human beings like that! Firstly, Nazi's believed that Jews were not quite human. They made much of such things as measurement of noses, ears etc that "showed" that people they regarded as being non-Aryan were "sub-human" etc etc. I hope that I have explained this clearly, and am not being unfair about what Hitler et al believed. Secondly, they forced Jews to wear the "Star of David" on their clothes. My question is this, if the Jews were as the Nazi's claimed they would have been distinctive enough for the Germans to identify them without the "Star of David". If the Jews had to wear a badge to identify themselves surely all the Nazi racial theory is complete b*****? How did the Nazi's justify forcing Jews to wear the badge? By this I mean what did they tell the rest of the Germans, those who were not complete fruit loops?
