Thank you for posting the essay, but I find it very difficult to agree with their conclusions. They walk past the entire backstory straight up to an agenda driven perspective, and it is very difficult to believe the two Jews who wrote this story are whitewashing anti-semitism.
Von Trapp's children would agree wiht you on Georg's character. When they first saw the production they objected, saying their father was nothing like the man portrayed in the film. And complained about it, loudly, to no effect.
And Herr Detweiler? He isn't a Jew. He is the straight up representation of Father Franz Wasner, a Roman Catholic priest who was Georg's friend, who lived with the von Trapp's, and becomes von Trapp Family musical coordinator. Wagner will accompany them on all of their tours both in Europe prior to leaving for America, throughout America, and later on world wide tours.
Problem, it is hard to make a Roman Catholic Priest have the same convictions of easy living portrayed by Uncle Max.
Fun fact, Franz Wasner will become the rector of
Pontifical Institute Santa Maria dell' Anima which was Alois Hudal's operation during and after WWII.
