Shachtman's youthful followers were able to bring new vigor into the party and Shachtman encouraged them to take positions of responsibility and leadership. As a young leader, Harrington sent Kahn and Horowitz to help Bayard Rustin with the civil rights movement. Rustin had helped to spread pacificism and non-violence to leaders of the civil rights movement like Martin Luther King Jr. while Kahn and Horowitz quickly became close assistants of Rustin. The civil rights movement benefited from intelligence and analysis of Shachtman and increasingly of Kahn. Rustin and his young aides, dubbed the Bayard Rustin Marching and Chowder Society by Harrington, organized many protest activities. The young socialists helped Rustin and A. Philip Randolph organize the 1963 March on Washington, where King delivered his "I Have a Dream" speech.
