Hitler wanted to promote the "master Aryan race" of blonde haired blue eyed people, but even in Germany, many Germans could not have passed this standard: large numbers looked Eastern Europe and French or other ethnicities. Hitler believed the people of Germany and other Germanic countries contained the most blood of the Aryans, but that their bloodlines needed to be protected and improved from the harmful intermarriages that had been ongoing for centuries.
So what was life like for a Germany citizen that looked like the wrong "racial background?" Were they ignored, drafted, given extra labor duties, the subject of more police targeting? Were there groups they couldn't join like the SS or others, even if their German bloodline was provable?
Was there real discrimination against them?
Did Hitler or anyone in the NAZI Party have a future plan to eventually clean out the ethnic diversity of the German populace?
