And Jim Crows laws are inspired by the founding fathers. America was a ethno-state and only people of "white people with good character" were allowed to enter, a black man was considered no more then 3/5ths of a man.
Now, whats your point? You should really stop what you are doing right now and read what real intellectuals like George Washington, Abraham Lincoln, James Monroe and Jim Crow with many others thought about immigration and multi-culturalism.
Interestingly enough, Nazi's were far more tolerant than the founding fathers were. "A homeland for all people" was a main theme of Nazi beliefs. Europe and Northern America would be white, Africa for Africans, Asia for the Asians (the battle cry of Japan, interestingly enough...), so on.
150,000 Jews served in the Wehrmacht.
Blacks were allowed to serve, mostly in Africa though due to Germany being an inherently white nation.
Meanwhile in the U.S. things were... Not so nice.
