Many atheistic books and blogs seethe with anger. Remarkably, the authors do not limit their anger to Christians. They seem most livid with God. I don't believe in leprechauns, but I haven't dedicated my life to battling them. I suppose if I believed that people's faith in leprechauns poisoned civilization, I might get angry with members of leprechaun churches. But there's one thing I'm quite sure I wouldn't do: I would not get angry with leprechauns. Why not? Because I can't get angry with someone I know doesn't exist.
