On a clear, warm day in late April, a dusty blue bus bearing the logo “Equality Ride 2006” drove toward the main gates of the United States Military Academy in West Point, New York. Overhead, a cloudless sky arched above the red-gray limestone campus, its Gothic towers perched on stony cliffs high above the Hudson River. Not far from the gates, the bus parked and discharged about 40 protesters in windbreakers or T-shirts.
