Next time someone tells you that, remind them that those norms are only 6–9 thousand years old, and they are not timeless and therefore sacrosanct. This is one of the major reasons that I write so much about our pre-patriarchal history, to demonstrate that this stuff is not the way it’s always been. Patriarchy has gone a long way to justify itself by feeding us propaganda to that end. Most people don’t know any better because they’ve never questioned it or even thought beyond their indoctrination. Still, that must be incredibly frustrating to hear that.
