The Nazi Party was birthed out of the belief that German Jews had sabotaged the war effort in WWII causing Germany to lose the war, and subjecting the nation to the humiliation under the Versailles Treaty. This became a core tenet of Nazi philosophy as they embraced the concept of Aryan racial purity as the prototypical German. From the onset, racial lines were drawn. Aryan included Germans, while non-Aryans included Jews, Gypsies, Slavs, Africans, etc.
From 1933 onward, the Nazis began identifying and separating these non-Aryans by taking away opportunities, depriving them of citizenship status, prohibiting who they could marry, and segregating them from Aryan Germans. All of this was done under the pretense of race. Or if you don't like the word race, then ethnicity (which means the same damn thing).
Take Gypsies for example. They were of darker skin, and thus singled out by the Nazis as non-Aryan. Yet in every sense of the (obsolete) word, Gypsies are Caucasians. So what's the difference? Religion? Can't be that. Gypsies are Christians. Country of origin? Nope. German Gypsies were born in Germany. As were their parents, grandparents, etc. So why single out Gypsies? Because they weren't part of the Aryan master race.
And then 1939 arrives. The with the invasion of Poland, the Nazis gain control of a population rich in Jews. Nothing tribal about it. They were Poles, first and foremost. But the Nazis chose to segregate that society, separating people along racial lines. Ghettos were built to segregate the Jews.
In 1941 came the invasion of the Soviet Union. At the same time, the "Final Solution" was drafted by Himmler, Eichmann, and Heydrich to address "the Jewish problem". 'Final' meaning death. Special units called Einsatzgruppen were formed for one reason and one reason only. To exterminate people based on race. And death camps were constructed in Eastern Poland to rid Europe of the non-Aryan Jews. Chelmno, Treblinka, Sobibor - these camps were build for one reason and one reason only, to wipe out a race of people.
This is clearly documented in every single thing that the Nazis ever said or published. And yours or Whoopi Goldberg's opinion on race doesn't have a damn thing to do with the reasons why the Nazis did what they did. Again, Nazis killed Jews because they considered them an inferior race and a detriment to their ideals for an Aryan Reich. It really didn't matter if they looked white to Whoopi Goldberg. To them, they obviously saw a racial distinction that separated them from their Aryan ideals, regardless of what religion they happened to practice.
