Tell Norman Wolfe ("Quran burning: Obama isn't the one who should be apologizing," March 2) that if you step on someone's toes, you apologize. If you run over someone's cat, you apologize. If you accidentally incinerate someone's book, especially a holy book, you apologize. Then you have laid the groundwork for countering or reacting to whatever vengeance the injured party has unjustly taken.
I think humility is a virtue. Respect for the other party, no matter how unjust or evil that party may be, is the preferred first step in a course of action.
