Thats not at all what I was pointing out. This story actually takes place in Brazil. He should be referred to by the name his people would use for themselves, for God's sake people, have some respect.
And if it is the case that you do not know a person's heritage use a term that is reflective of that (your lack of knowledge) instead of using some archaic misconception just because it has become the status quo.
THIS MAN does not live like any person today. He is not even an "American Indian". Your "American Indians" all speak english, or another modern language, and they are integrated with society (hence they could be interviewed in the first place) and they are not this man and they do not speak for this man or his people.
Hell, it's 2010 and with a story like this we actually had the chance to get the "discovery of a new peoples" thing down right this time with respect. The gov't of Brazil realizes this and the steps they have taken to insure this mans safety back that up. This story completely blows the humanitarian aspect though, rather than preserving it.
Why? Because he is way more native than any of the "American Indians" that you are referring to but you just completely don't get it. He is unique. He is an authentic native to his territory. He should be called by his tribal name, failing that he is a native or indigenous person and that is all that we really know.
