This was news to me. I just saw a clip of Julian Bond talking on the first GLBT panel at an NAACP convention, and he quotes Bayard Rustin as saying, MLK "couldn't organize vampires to attend a bloodbath" when they started working together.

The Wiki entry:
Bayard Rustin (March 17, 1912 – August 24, 1987) was an American leader several social movements for civil rights, socialism, pacifism and non-violence, and gay rights.
In the pacifist Fellowship of Reconciliation (FOR), Rustin practiced nonviolence. He was a leading activist of the early 1947–1955 civil-rights movement, helping to initiate a 1947 Freedom Ride to challenge with civil disobedience racial segregation on interstate busing. He recognized Martin Luther King, Jr.'s leadership, and helping to organize the Southern Christian Leadership Conference to strengthen King's leadership; Rustin promoted the philosophy of nonviolence and the practices of nonviolent resistance, which he had observed while working with Gandhi's movement in India. Rustin became a leading strategist of the civil rights movement from 1955–1968. He was the chief organizer of the 1963 March on Washington for Jobs and Freedom, which was headed by A. Philip Randolph, the leading African-American labor-union president and socialist.<1><2> Rustin also influenced young activists, such as Tom Kahn and Stokely Carmichael, in organizations like the Congress on Racial Equality (CORE) and the Student Nonviolent Coordinating Committee (SNCC).
After the passage of the civil-rights legislation of 1964–1965, Rustin focused attention on the economic problems of working-class and unemployed African Americans, suggesting that the civil-rights movement had left its period of "protest" and had entered an era of "politics", in which the Black community had to ally with the labor movement. Rustin became the head of the AFL–CIO's A. Philip Randolph, which promoted the integration of formerly all-white unions and promoted the unionization of African Americans. Rustin became an honorary chairperson of the Socialist Party of America in 1972, before it changed its name to Social Democrats, USA (SDUSA); Rustin acted as national chairman of SDUSA during the 1970s. During the 1970s and 1980s, Rustin served on many humanitarian missions, such as aiding refugees from Communist Vietnam and Cambodia. He was on a humanitarian mission in Haiti when he died in 1987.
Rustin was a gay man who had been arrested for homosexual behavior early in his life. Because homosexuality was criminalized through the 1990s and stigmatized through the 1970s, Rustin's sexuality was criticized by some fellow pacifists and civil-rights leaders. From the 1950s through the 1970s, Rustin was attacked as a "pervert" or "immoral influence" by political opponents, both segregationists and Black power militants. To avoid such attacks, Rustin served only rarely as a public spokesperson. He usually acted as an influential adviser to civil-rights leaders. In the 1970s, he became a public advocate on behalf of gay and lesbian causes.
