A couple of takes on the Whitesboro seal and what they tell us:
The "Whiteburros" seal is a satire, but it makes an important point. If the real seal shows a friendly wrestling match, then revise it to show both sides as equals. Or the Indian as the superior. Putting the white man in the superior position sends a racist message--whether the town of Whitesboro realizes it or not.
Would any white folks accept this as a seal even if it accurately reflected their history? Then why do you expect Indians to accept an image of an Indian in an inferior position? There's no logical consistency here--just "whites get to show themselves winning because of white privilege."
