So, here is the real truth of the matter, for those with an open-enough mind:

Men are naturally (in the true sense of the word) physically designed to dominate human society. The main developmental vector for this is the effect of testosterone, which starts right in the mother's womb, where a tremendously sneaky genetic trick causes the mother to produce testosterone to help male formation of the foetus.

Testosterone causes men to develop with larger physical structure - stronger bones, larger muscles. It also causes men to be more aggressive - testosterone is a potent psycho-active drug too.

All of this was presumably valuable in human evolution - and almost certainly because lengthy human gestation and helpless state of the infant at birth required a protection 'service', the male.

The tax for this protection during pregnancy and early childhood is male physical dominance.

We can reverse this with hormonal therapy, at which time females will start displaying the same behaviour.
