Protest, even more than property, is a sacred resource of American society. It begins with radical minorities at the margins, eventually marching into the mainstream, where their views become the majority sentiment. Prophetic minorities instigated the American Revolution, ended slavery, achieved the vote for women, made trade unions possible, and saved our rivers from becoming sewers. Protest by its nature challenges authority. It cannot be managed or commodified without losing its essence. Copyright © 2004, Newsday, Inc.
