"American Indian" is an official term, and moreover it is a term DESIRED by some aboriginal rights activists in the United States, like the founders of the American Indian Movement (AIM).

Uhm, quite a lot of tribes would disagree with you. American Indian is preferred by many.

Also generalizing to all native Americans everywhere is sort of a needless display of ignorance.

This comment sums up what Hacker News has become perfectly.

Front and center is the sentence correcting some slight, inconsequential anachronism that has nothing to do with the overall point of the comment and only serves to show the perceived intelligence of helpfulness of the commenter. Then there is a short sentence, more of an afterthought, addressing the point of the comment.

My point was more about the redundancy rather than an attempt to be pedantic or politically correct, but go ahead and downvote...
