It was March of 2003. New York City protested against Bush's invasion of Iraq. 200,000 showed up; I was one of them. I was almost trampled by a horse-mounted police officer. The diversity was as wide as could be humanly imagined, the intensity clear, the unity so complete. I have been in many protests, including the Vietnam war in my college days, but nothing matched this day’s importance and its singularity of purpose; it truly was an event for human beings.
