Men are inherently more violent. The vast vast majority of gang killings are done by men.

Genghis Khan raped enough women in his life, that 10% of asian men are direct descendents of him.

Genghis Khan - "The greatest joy for a man is to defeat his enemies, to drive them before him, to take from them all they possess, to see those they love in tears, to ride their horses, and to hold their wives and daughters in his arms."

The Spanish Inquisition with all their creative torture was men.

The Holocaust.

Women just don't have this capacity for cruelty and violence.

We are not psychologically equal in this respect. It just seems very misguided to argue otherwise.
