> He makes up a story about why Europeans are dominant, not dominant now, in this time, but forever.
He never claims the dominance will last forever. He just presents theories as to why Europeans are dominant now (or were 40 years ago when the book as published at least).
It’s not racist to try to explain why Europe conquered New Guinea and not the other way around. It’s racist to say that’s a good thing or destined or will last forever, but Diamond never argues that. I think you have some headcanon there.
