I can at least attest to it from second hand stuff told to me when I was out on the reservation. There is still plenty of misogyny and rigid gender norms but the women elders have a sort of veto power in the tribal councils or at least traditionally. The men all, for example decide on weather to make war or some other consequential thing and then the women are allowed to be like "no that's dumb wtf is wrong with you" if they all agree to.
