Secretary of State Hillary Clinton said Tuesday that gay rights are human rights and pledged to defend those rights at home and abroad.

“Just as I was very proud to say the obvious more than 15 years ago in Beijing that human rights are women’s rights and women’s rights are human rights, well, let me say today that human rights are gay rights and gay rights are human rights, once and for all.”

The standing-room-only event was co-hosted by the State Department's Office of Civil Rights and Gays and Lesbians in Foreign Affairs Agencies (GLIFAA), a group that represents the agency's LGBT members.

Clinton reminded the crowd that discrimination and prejudice against gay men, lesbians, bisexuals and transgender people persists.

“Think about what's happening to people as we speak today. Men and women are harassed, beaten, subjected to sexual violence, even killed, because of who they are and whom they love.”

“In some places, violence against the LGBT community is permitted by law and inflamed by public calls to violence; in others, it persists insidiously behind closed doors.”

“These dangers are not 'gay' issues. This is a human rights issue,” she said to loud cheers.

She also took the opportunity to highlight some of the gay rights initiatives advanced in the Obama administration, the State Department in particular, and announced that for the first time gender identity will join sexual orientation in the agency's equal opportunity statement.

“Our work is demanding and we need every person to give 100 percent,” she said. “And that means creating an environment in which everyone knows they are valued and feels free to make their contribution.”

President Obama and Vice President Joe Biden also will host a gay pride celebration Tuesday evening at the White House.
