I think the persistent reference to Napoleon Chagnon should be something everyone should question, considering the harm that Chagnon engaged in across the planet.

I mean, it's worth reading Marshall Sahlins' criticisms of Chagnon (and also Sahlins' resignation from the National Academy of Sciences after the election of Chagnon). Chagnon was a shit-stirring bastard who produced fraudulent "research," so referencing things that focus on supporting him should be an immediate question.
