The quotes about the feather:
> This essay introduced a few examples of Indian warriors with full headdress, but what if just one feather is presented—is it sufficient to conjure images of savage warriors? Well, probably not just one feather, unless it can be associated with some other stereotypical image. In this case, what if the feather is paired with the word “Apache”?
> It is interesting that the Apache Web site provides a link to a Web site devoted to the Apache people, providing “stereotypical proof” that the feather symbol and the foundation name are designed to evoke images of the Apache people. This is all the more interesting in light of the fact that perhaps history’s most photographed Indigenous warrior—the Apache Geronimo—was not inclined to adorn himself in this fashion. In fact, even Hollywood depictions of Geronimo eschew the feather look. Yet the stereotypical image of the feathered Indian persists.
