I would nominate Harvey Milk because he did so much to further LBTQ rights.
"Milk served almost eleven months in office, during which he sponsored a bill banning discrimination in public accommodations, housing, and employment on the basis of sexual orientation. The Supervisors passed the bill by a vote of 11–1, and it was signed into law by Mayor
George Moscone. On November 27, 1978, Milk and Moscone were
assassinated by
Dan White, a disgruntled former city supervisor who cast the sole vote against Milk's bill.
Despite his short career in politics, Milk became an icon in San Francisco and a martyr in the gay community.
[note 1] In 2002, Milk was called "the most famous and most significant openly
LGBT official ever elected in the United States".
[2] Anne Kronenberg, his final campaign manager, wrote of him:
"What set Harvey apart from you or me was that he was a visionary. He imagined a righteous world inside his head and then he set about to create it for real, for all of us."[3] Milk was posthumously awarded the
Presidential Medal of Freedom in 2009."
