The LGBT equality movement is an exercise in self-empowerment. http://slog.thestranger.com/slog/archives/2011/09/20/sisters-doin-it-for-themselves
From the linked article, so you don't have to read it all:
"Likening the gay movement's triumphs in federal court and the military to the civil rights movement's accomplishments obscures the real meaning of what the gay movement has achieved. And how America has changed in the six decades since Harry Truman courageously signed that order and Justice Earl Warren persuaded the Supreme Court into unanimity on the unconstitutionality of racial caste. No politician—no president and no Supreme Court justice—put his or her political capital and power behind the gay victories in the military and the courthouse. The gay movement won them, and continues to win them, largely by itself.
It's a bootstraps movement."
