If only our Founding Fathers could have appreciated what a truly American spirit was! It's so sad to say about people you love and admire, but only greed and prejudice could keep such brilliant men from seeing the obvious.
People who don't read history books are unaware that a huge number of "cowboys" driving herds to the railheads in Kansas were Indians. And many don't know that some of "Indians" who raided the drives for beef in the the "nations" were runaway slaves and ex-slaves adopted into the tribes in the Oklahoma territory. Western movies don't tell you that.
