This has been mentioned before but it's worth mentioning again - there is pretty much no advanced civilization that is also a matriarchy. Anytime someone points out to you about how there's some obscure primitive tribe out there where women call out the shots and how it's a wonderful hippy paradise full of free love and no war also ask them about if any of these societies have running water, science, great art, universities, museums, electricity etc.
