The blanket statements you have made about egalitarian cultures are simply not true. It depended on the culture. Each was as different as cultures are today.

The example I gave of the Iroquois clan mothers - no, they did not practice female circumcision.

And I wouldn't conflate polygamy with equality. All of our early ancestors were polygamous.

As far as Stanton's "white supremacy" goes, that's more than a tad hyperbolic. White supremacist groups didn't exist in 1845. The KKK was not established until 1865. Yes, their beliefs were there long before that date, but calling Stanton a white supremacist doesn't match the timeline.

Either way, I already addressed Stanton's lack of intersectionality.
