McGrath seems to be spewing low-key high-grade wisdom all over the place lately. What about those people who say what you'd like to say, but they always get there first?

I like argument for sport. Debate teams are good for kids. A friend of mine gets deflated because his wife will take up his side when they argue, and out-classes him. What's really awful is to argue with someone who doesn't see their own side-- you can't get into the spirit of it because you want to help them.
