I recently participated in a commemoration of Martin Luther King’s address “Beyond Vietnam—A Time to Break Silence,” originally delivered on April 2, 1967, at New York City’s Riverside Church. King used the occasion to announce his opposition to the ongoing war in Vietnam. Although a long time coming in the eyes of some in the antiwar movement, his decision was one for which he was roundly criticized, even by supporters of the civil rights movement. He was straying out of his prescribed lane, they charged, and needed to get back where he belonged.
