October 21, 1967. Antiwar protesters participating in the March on the Pentagon include students, veterans, longtime radicals and pacifists, and many activists who have been or still are active in the civil rights movement, especially religious organizations.
One such religious organization is Clergy and Laymen Concerned about Viet Nam—National Emergency Committee (CALC), led by Rev. Richard Neuhaus, Rabbi Abraham Heschel, Father Daniel Berrigan, and Dr. Martin Luther King, Jr. Dr. King delivered his ‘Beyond Vietnam" speech condemning the war under the CALC auspices on April 4, 1967 and accepted the position as co-chair soon after.
Dr. King did not support organized draft evasion, mass civil disobedience, or confrontational rhetoric, however. He is not present at the October 21 march, and indeed the larger civil rights movement is divided about how much to support the antiwar movement.
