Yesterday, while I was standing in line in the post office, people who had never previously met were arguing passionately about the slaughter in Lebanon. It reminded me of 9/11, except the conversation had flipped over somehow. On 9/11, the Muslim family that owns the corner grocery was practicing community diplomacy, handing out free sodas and assuring nervous neighbors that terrorism wasn't part of their culture. Yesterday, non-Muslims were promising their Muslim neighbors that the U.S. doesn't support the murder of civilians.
