Teaching your kids how to argue doesn’t make them quarrelous; it makes them consider other points of view, particularly those held by others.
Let’s face it: Our culture has lost the ability to usefully disagree. Most Americans seem to avoid argument. But this has produced passive aggression and groupthink in the office, red and blue states, and families unable to discuss things as simple as what to watch on television. Rhetoric doesn’t turn kids into back-sassers; it makes them think about other points of view.
I had long equated arguing with fighting, but in rhetoric they are very different things. An argument is good; a fight is not. Whereas the goal of a fight is to dominate your opponent, in an argument you succeed when you bring your audience over to your side. A dispute over territory in the backseat of a car qualifies as an argument, for example, in the unlikely event that one child attempts to persuade his audience rather than slug it.
