No, saying that even in the paleolithic they were adapted to wildly different diets, because they were intelligent and they could make the most of whatever grew near them. http://hells-ditch.com/2012/08/archaeologists-officially-declare-collective-sigh-over-paleo-diet/ If they found wild rice, that was okay. If they found whale blubber, that was also OK.

So you're claiming that any human will be just as healthy on any diet?

Come on, you are smarter than that, you know the difference between biological sex and social gender. E.g. https://en.wikipedia.org/wiki/Albanian_sworn_virgins

So you're arguing that the Albanian sworn virgins were (socially) men? The very fact that they were called "virgins", thus appealing to the ideal of female virginity, should give you a clue. I thought you were smarter than that.

Popular versions, yes, but they are not caricatures simply - more like what people actually believe in. Popularity matters.

Depends on which people. What the followers of the philosophies believe matters, what most people believe about the followers, not so much.

This jaded view was already disproved by Plato. Justice and efficiency go hand in hand and there is rarely lasting success without a lot of cooperation and fairness.

I'm not sure who you think your arguing against here. It certainly isn't (most of) the philosophies you listed.
