Evolutionary biases simply aren't relevant structurally. While men do exhibit more violent behaviour, it's been since the invention of the state that violence became a tool and not a concern. The vast majority of violence has for a long time been organized, calculated state or political violence, not instinct-driven agression. The latter still exists, but pales in comparison.

Put another way, if you took almost any society today and made everyone women, you would not see a major decrease in violence, as the vast majority of violence done serves structural and material reasons.

While violence is not always a tool, it is an evolutionary strategy. Before the advent of the state, it was already a tool, or could be at least. It, and other adaptive behaviors still hold some sway on us, and our societies are still shaped by them. We've become more complex, and cultural evolution influences as well, but you cannot cross this a defunct relic of our history.

I agree with your second point though.
