Researchers Divided Over Whether Anasazi Were Cannibals
"Archaeologists argue bitterly over whether the ancient Anasazi, the ancestors of today's Pueblo Indians, routinely killed and ate each other. From one point of view, the evidence seems overwhelming: piles of butchered human bones, some of which were apparently roasted or boiled. In one instance, ancient human feces even seem to contain traces of digested human tissue."
Doesn't leave much logical space for the "other" point of view does it?
Maybe the other point of view is Lefty academics putting their fingers in their ears and going "la-la-la-la!"—and hanging nooses on their own office doors. As one academic pointed out at the link you posted from National Geographic:
Tim White, an archaeologist at the University of California, Berkeley, who worked with Darling [an anti-Western archaeologist] on one site, argues that . . . archaeologists go out of their way to avoid the cannibal explanation.
