It was like back in the day in Catholic schools, if two guys had a beef, the priest would give them both boxing gloves and they would fight it out, and in the end, wind up respecting each other.
Between you and me... my son’s football team still has a policy similar. If you have a beef and can’t resolve it, the coaches will take you off campus and let you resolve via fighting. Thus far, no one has taken the coaches up on the offer but I don’t see anything wrong with it.
