I would go so far as to say that motherhood is the reason there is unequal treatment of the sexes across the world. Pregnancy, birth, and childrearing are the reason men all over the world are in charge. I'm sure it's been happening for thousands of years. Men are in charge because they can be. They aren't saddled with reproduction and childrearing. They set up the world to work for them. I'm reaching a point in my thinking where I feel a matriarchal society like elephants have is the only healthy way for females of a species to live.
