Good essay.

One thing I have to take issue with: "Every major war that has been fought has been waged by men."

I know Margaret Thatcher and Queen Elizabeth I were pretty butch, but those
are just two examples off the top of my head. I'm sure there are plenty women who have been head of state during wars their country was involved in.

Also, diverting a bit, I suspect that women's violence towards men and children has also been greatly under-reported, due to embarrassment or fear.
