Teaching kids to argue is like issuing each of them a personal sword and teaching them to fence. At first, they are all excited with the weapon in their hand. They wave it around, wildly slicing the air and make sound effects as they play with their new toy [it's NOT a toy].
When the excitement has died down and they are calmer, maybe they will start paying attention to the rules of the sport. The most important rule: stop looking at your opponent's sword. As fun as it may be, the score is not counted by the number of times you hear the sound of metal hitting metal.
In this game, you keep your eyes on the target. You win by stabbing your opponent through the heart.
