You do realize that you haven't actually addressed, much less refuted what she's said, right?

And "Warri and Yatungka" are a couple who spent time living nomadically in the desert who died in the 1970s. What exactly do they have to do with the components of what makes up an egalitarian culture - which is what this story is about?

Did you complete miss the parts where she repeatedly said that egalitarian cultures are not Utopian or "perfect" in any way? Honestly, it's like you didn't actually even read the story but were just looking for an outlet for your belligerence. Pathetic...
