I was exhausted and on my way home from Phoenix, where I participated in a protest against Focus on the Family’s ex-gay Love Won Out Conference. One of the few remaining joys of flying these days is reading without all of the earthly distractions, such as cell phones and e-mail. At least until the terrorists figure out how to make a newspaper bomb, and then we will be left with nothing to do but twiddle our thumbs while we levitate.
