Why? Most modern human behavior is nurture. Men's brains are not noticeably different from women's.

Nurture is literally the null hypothesis. Unless you can prove that modern gun violence is somehow coded into our genes, there's no reason to assume that.

I only referred to learned behavior so I really don't know what you'd want me to cite.

&gt;Nurture is literally the null hypothesis

The male sex is the more aggressive one in all related species. The hypothesis that the human male is the more aggressive one because of some huge coincidence should not be your null hypothesis and even if it was, that wouldn't make it fact.
