Indian

reaction: which one? or is the ambiguity the point?

response: used to describe large, noncohesive groups of people - persons whose ancestors come from the Indian subcontinent, and persons whose ancestors come from the Americas (well, sort of. MY ancestors come from North America, including the ones whose ancestors came from Germany, Ireland, France, Scotland ... shoot, if you go back far enough, we're all African.) None of the ancestors regarded themselves as part of a homogeneous group, but the term is convenient except for the unfortunate duplication due to Columbus being hopelessly lost. I wish there were different terms for the two groups, but the PC Native American is cumbersome. I don't know if there is a similar phrase used in India.
