We (as a culture) have spent centuries stamping out trial by violence and duelling because as a dispute resolution mechanism it overwhelmingly favors young men with training.

We have in recent years marginalized boxing as it gets people killed or seriously injured, causes lasting brain damage even under controlled circumstances, and normalizes violent behavior.

Edit in reply to sibling: HN seems to have some anti-deep-thread mechanism which hides reply links. Maybe you should find someone to punch about that.
