Wikipedia’s bio on Bayard Rustin:
Bayard Rustin (March 17, 1912 â€“ August 24, 1987) was an African-American civil rights activist, important largely behind the scenes in the civil rights movement of the 1960s and earlier and principal organizer of the 1963 March on Washington for Jobs and Freedom. He counseled Martin Luther King, Jr. on the techniques of nonviolent resistance. Rustin was openly gay and advocated on behalf of gay and lesbian causes in the latter part of his career.
A year before his death in 1987, Rustin said: “The barometer of where one is on human rights questions is no longer the black community, it’s the gay community. Because it is the community which is most easily mistreated.”
