To me, pied-noir means Latins (mostly) who returned to uninhabitable regions of Algeria to make them agriculturally-viable again. They're more indigenous to such resettled parts of Algeria, than the Arabs and Berbers who had migrated there with their goats to denude the place. In America, "blackfeet" refer to a likewise not-quite-nomadic inhabitants of a region. Here too: how indigenous are they?

The /pol/ cartoonist Stonetoss, part Taino, has Opinions. Mostly focused on the Navajo, whom Hopi would consider "settlers"; one might also look to the transplanted Lakota and the imperial Comanche.

Geneticists could tell us. h/t Sareceni: Science.org is reporting on a partnership between geneticists and the Blackfoot. [UPDATE 4/9: here, the results.]

I see a conflict between impartial scientody and interested parties. We are assuming that the Blackfoot are virtuous and "belong" there. In rhetorical studies this is, I believe, known as Begging The Question.

Even if we weren't breaking the logical rules, suppose the fossil-fuel companies decided to bankroll their own studies.
