It is not our right to punish one for thinking as he does, no matter how much we disagree.

Read things you're sure will disagree with your current thinking. If you're a die-hard anti-animal person, read Meat. If you're a die-hard global warming advocate, read Glenn Beck. If you're a Rush Limbaugh fan, read James W. Loewen's Lies My Teachers Told Me. It'll do your mind good and get your heart rate up.

You can disagree but do not fight.
