Hi, this is a very important and interesting article. I am from Australia, so I know very little about the origins or correct uses of the terms Latino, Hispanic, etc. and was even ill-informed about who came under the 'Native American' tag. Your article makes it all so much clearer.
Here, in Australia our own indigenous population have undergone a number of name changes over the years: Aborigines, Aboriginal, Indigenous Australians, and now First Nation people. I think it is important for all people to be able to define exactly what they want to be called.
