I had a literature class with a professor who asserted that the world would be more fair and peaceful if society was matriarchal. There were many discussions where I disagreed.    Many people cite bonobo monkeys as an example of a matriarchal society. All the members of the monkey tribe are effectively bisexual, and sexual acts are a way of bonding. I suppose, instead of fighting between males, like most other animal species functions, this is more peaceful.    At the same time, we are not bonobos. Maybe humans are meant to function in our own natural society, even if that means that we naturally trust and select leaders who exhibit masculine traits. Our closest primate relatives, chimpanzees, demonstrate organized warfare! If we select leaders based on masculine traits, then that's what we do; if we are a warlike species, that's what we do. Liberals are all about what's natural until it conflicts with their views.
