That's funny but do you people realize that women, in groups, actually synchronize their menstrual cycles? That alone in a female-run society could lead to warfare on a previously unknown scale!
While I enjoy a joke as much as the next guy, the deleterious effects of female influence on public policy is no laughing matter.
Even the Bible recognizes the disaster of women in positions of power. The book of Isaiah declares women and children as rulers to be a punishment from God.
