Right – I recognized that not all Eskimos were Inuit, and I saw the Wiki article but thought to come to a better source (i.e., here). I find it odd/counterintuitive that there’s a group term that may cause offense to those people, but no general generic term has come up in its place. I don’t think getting specific down to a specific group will cut it, as there were multiple groups participating in the subject of the sentence.
I guess a big part of this is my assumption that Pygmy is possibly offensive, in that it’s Greek origins suggest a colonialist/Western background and it also carries something of a pejorative connotation (i.e., short people).
