An era of matriarchy?

[Ciel_Rouge]

primate physiology make the women statistically very likely to be substantially weaker than the average men in her society in terms of upper body strength, track and field type exercise, and advanced spatial perception.

This does not make any individual woman less suited to lead in most modern circumstances, but it does explain the stereotype of women not possessing martial virtue which have long been regarded as the most basic role of the leader.

Advanced spatial perception is impaired by hormonal issues too. Many women have an unhealthy lifestyle - stress and malnutrition - or take contraceptives which clearly make them weak and disoriented. We are related to monkeys etc. but we are NOT monkeys. Maybe we are built in a much more egalitarian way but only suppress it. There are women climbing the Mount Everest etc. so maybe they are not as incapacitated as we think.

The Amazons possessed martial virtue.

Besides, in a matriarchy men would be warriors subordinate to a female ruler. I suppose it is often a very natural course of action. A relic of this are women ordering men to beat somebody up - happens very often in present day society.

Why would being wise or advanced lead directly to egalitarianism? Why couldn't Atlantis (lulz) have been full of brutal patriarchs?

Because they would be advanced enough to realize that the suppression of any social group does not bring any serious gain. It only leads to them performing much worse at whatever they are doing and also leads to them craving mutiny at some point. It is not only about women but even teenagers etc. - sometimes there are teenage geniuses etc. who are suppressed and sent to hospital. Imagine a civilization where everyone is allowed to contribute to science, technology etc. and where teenage geniuses are allowed to work legit instead of forcefully making them retarded and ignoring just because it is the "wrong age" to be smart.

There is one branch of life which already does that - in classical music you have "prodigies" who are allowed to study with grownups and treated seriously even if they are only 7 or so.

A strong society, powerful scientifically and economically, is one where all members can contribute freely. In Islamic countries women are suppressed. And the Islamic countries do not have very advanced science nor a space program. They do hower often seem to have advanced frustration.

Regarding breasts and what could be so special about them Well, all this social conditioning seems to stop working once a woman is drunk. Drunk women display their breasts when they are happy or excited etc. and they are also much more active, assertive and dominant in their behaviour towards men. Social conditioning destroys their confidence and forces them to wear a bra and always cover their titties etc. even though they still tend to display them with low necklines etc. All this smells a lot like a relic of a time when women could display their natural behaviours more freely. In Islam they are even forced to cover their face. It is not natural. Similarly, bikini suits were a shock at some point but aren't any more. I read of protests of women in Japan who wanted to publicly go without a bra when the weather was very hot since men are allowed to display their upper body and can thus prevent overheating. So breasts seem to be special, covering them seems unjustified especially in a form of wearing an undergarment which often is uncomfortable and does not allow for proper ventilation.
