Well then I guess we should hate everybody.
If you study tribal names, or what people call themselves, they translate to the following:
The People
The Real People
The Chosen People
The Special People
The Real Human Beings
The Civilized Ones
And so on and so forth
This is memorably captured in "Little Big Man," one of my favorite movies, where the tribe calls itself simply "the human beings."
And their names for the next tribe over usually go back to "the other people," or "the evil people," or "those cannibals over the hill."
One of the enduring controversies in American anthropology is what to call the pre-Columbian cliff-dwellers in the Four Corners region, whom Westerners have traditionally called the "Anasazi." Anasazi is a Navajo word that means, more or less, "our ancient enemies." The Hopi, who consider themselves the descendents of ... um, those folks, still bristle at the name.
