Note also that men are not situational and geometrical defficient compared to women either, so as equals there, men win with strength obviously. Women win with sluty politics, deception and chance. Women are more masterly in stealth than in brute strength.
I have always trained with women, and always gone easy on them. Otherwise, it would be messy.
The only martial art that might be helpful for them would be Wing Tsun, which was developed by a woman and with the goal of defeating a man. Shorter arms are an asset, the style does not require great strenght or stamina, no fancy face kicks or spinning back kicks. Again, it would only work against an untrained man.
