According to Hirsch's book, their musical touring life was abruptly halted when Hitler invaded Austria. The Captain brought his family together and said, "We are standing at the open grave of Austria." He asked them if they wanted to stay or to leave. Despite the hardships sure to face them, they had no moral choice but to depart. Although it was a terrible blow to leave their home and all their belongings behind, when they learned that Himmler himself had taken over their house, their grief was almost unbearable.
In 1938, Austria was annexed to Adolf Hitler’s German Empire - the Anschluss of 1938 - and unlike many Austrian aristocrats, the Von Trapps were horrified. Georg made no secret of his feelings; allegedly, the Gestapo ordered the von Trapps to display the Hakenkreuzflagge (swastika flag) for Hitler's visit to Salzburg, but Georg replied, "I can do a better job with one of my Persian carpets." "Three times he refused the Nazis," said Renaud Doucet, the director of the Sound of Music show in Vienna. Twice he refused to become the commander of a U-boat, and command of a submarine base. "I have sworn my oath of loyality to only one Emperor" was his answer, and von Trapp rejected the offer.
And then he refused to sing at Hitler's birthday party. With that third refusal, the family realised they had to get out. They took a train and crossed into Italy, and at midnight on the same day, Hitler closed the borders." The von Trapps later learned that Heinrich Himmler, the head of the Gestapo himself, had moved into the family home."

Do you really think that the horrors of the Nazi regime were not "race related"? Do you really think that Von Trapp left his homeland and everything he owned to come to America where he had no family or friends or career, because he just didn't feel like working for the third reich? He abhorred their policies and he was afraid that his family would pay for his refusal to join the reich.
The goal of the Third Reich was to "cleanse" the world and make it an aryan (white) one. They didn't consider Jews to be "white". Blonde hair and blue eyes, that was white. And if you look at the demographics of Austria in the 1930's, there was no African (black) presence at all.
I am an actress and there are many roles I would love to play but realize that I simply am not suited, I am not saying that this actress is not a good actress and a wonderful talent. I'm also not saying that you couldn't cast her and have a terrific production of "The Sound of Music". But you will be changing the context of the story.
