http://www.thenation.com/doc.mhtml?i=20050328&c=3&s=houppertSheehan is a perfect example of the kind of folks peace activists insist are part of a silent majority: She opposed the war but was disinclined to speak out. "I was stunned and dismayed when the United States invaded Iraq," Sheehan says. "I didn't agree with it. I didn't think it was right, but I never protested until after Casey was killed." She pauses and steels herself for what feels like the hundredth brutal mea culpa: "And I am very sorry I didn't." Taking to heart the old union slogan "Don't mourn, organize," Sheehan is clearly deeply immersed in both. Along with dozens of other families who lost soldiers in the war, she formed a new organization, Gold Star Families for Peace, and has made it her penance to share the details of her own experience. "Now I am doing anything I can to shorten this war and save other families the pain we're going through," she says.
