I often feel like a referee at a hockey game. I toss the puck down and flee for my life while contestants more agile and accomplished than I am whack away at the puck. Unlike the referee, I'm not often entirely neutral in the ensuing contest. Like everyone else, I tend to cheer for those who are clever enough to agree with me on everything. But that doesn't mean that I'm not grateful to those who hold up the other side of the argument with zest and conviction.
You know the one about the fellow he told his friends: "I went to brawl the other night and a hockey game broke out." Well, the latter is always preferable to the former, so whack away, but don't break any hockey sticks on each other.
