I’m not sure what feminism has to do with polyamory or myths of the noble savage as expressed in this article. I mean, other than to suggest that polyamory and noble savage myths are tools of feminism to bring about the destruction of the patriarchy and/or men.

Which is just nuts.

Polyamory is a lifestyle choice. Polyamory has been around for millenia before feminism so one clearly has nothing to do with the other.

Noble savage myths are mostly a construct (created by a man) attempt to come to terms with the violence and erasure done to indigenous cultures. This viewpoint came about before women had access to education and professional research opportunities so it predates feminism (proper) as well.

I also fail to understand why one would think that an egalitarian tribe would not also have violence amongst individuals or why egalitarian tribes wouldn’t war with other egalitarian tribes under certain circumstances. Further, it does not automatically follow that warring behavior must also always accompany violence against women within the tribe. I would also guess that women in these tribes were quite capable of their own bouts of violence should the occasion warrant. In a sense, they were more suited and primed for it than women today.

Human behavior is complex, nuanced, and adaptive. I would think over the course of time, just about any iteration of organization has been/could be tried. If I had to make a guess, I would say that the spread of religious myths, particularly from the Abrahamic cultures are most directly responsible for the persistence of hierarchical structures based on male dominance rather than it being a superior and inevitable form of organization.
