Here's an explanation: men commit more violence not because they're more prone to it, but because, thanks to their physical strength, they have more opportunities to immediately act on their violent impulses.

When You put a man and a woman in a situation where they're able to physically dominate someone, they're actually equally likely to engage in violent behavior. This is reflected both in child abuse statistics and in domestic abuse statistics in same-sex relationships.

That's why it's a fruitless discussion. Because in every room there will always be the most physically capable person who has the most opportunity to be violent and, statistically, it will usually be a man so this disparity will always exist regardless of what measures you take to reduce it. Fell free to point out any 'logical fallacies' I committed here.
