&gt; When you look at the subject of aggression there is no more important factor than gender. Something like 90 percent of the people in prison for violent crimes are men. Men have different brains than women, which comes from our different roles during evolution, when the brain was formed. Men had a role of being aggressive, which makes no sense for a woman because a woman was not endowed with the physical strength of a man, who probably outweighs her. But although 90 percent of those in jail are men, 90 percent of people who have been awarded medals by the Carnegie Institute for heroism are also men.<p>What is wrong with this guy? Doesn&#x27;t he know that gender is a social construct?
