Mr Taylor, you touch on some good points.  However, fundamentally, you are wrong. The logical extension of your argument is that native writers and artists can only legitimately write about native people, people of African background are restricted to "their" particular background, whites can only write about whites (and their particular subset of whites at that) etc. You would ghettoize everybody. I fully agree that the depiction of native people by non-native writers and artists has frequently been insulting and racist. The answer is to educate and demand sensitivity; it is not to put up walls and declare your culture off-limits to anyone who cannot demonstrate some kind of genetic link to that culture.
