Full equality for gays and lesbians is the civil-rights issue of our time.

Men and women who want to preserve and protect the ideals of this nation are being booted from the military because of who they are. Same-sex couples who seek the recognition of their relationships that their heterosexual counterparts take for granted are denied the rights and responsibilities that come from civil marriage.

Ending these and other forms of institutional discrimination based on sexual orientation requires leadership. Pity there’s not enough of it coming from either end of Pennsylvania Avenue.

President Obama ran as a candidate of change. Perhaps no other community took that to heart more than the gay community. Obama promised to end “Don’t Ask, Don’t Tell” policy, which prohibits members of the military from serving if they are openly gay. He promised to repeal the so-called Defense of Marriage Act, which defines marriage as between a man and a woman and denies married same-sex couples more than 1,100 federal benefits available to opposite-sex couples.

There’s been no visible movement on either pledge.

As he has in the past, Obama said the right things on gay rights at last weekend’s fund-raising dinner for the Human Rights Campaign. “I’m here with you in that fight” for equality, he said. “For even as we face extraordinary challenges as a nation, we cannot — and we will not — put aside issues of basic equality.” On gays in the military, Obama mentioned his discussions with the Pentagon and the legislation pending in Congress and stated plainly, “I will end ‘Don’t Ask, Don’t Tell.’ That’s my commitment to you.” On repealing the Defense of Marriage Act, the president said, “I believe strongly in stopping laws designed to take rights away and passing laws that extend equal rights to gay couples.”

Frustration with Obama and the lack of progress in fulfilling his pledges on gay rights were evident at Sunday’s National Equality March. But why is he the only target?

Overturning “Don’t Ask, Don’t Tell” and the Defense of Marriage Act require legislation. House Speaker Nancy Pelosi, D-Calif., and Senate Majority Leader Harry Reid, D-Nev., have been content to sit on the sidelines while Obama takes the hits.

This can’t continue.

Pelosi and Reid must exert the necessary leadership in their respective chambers to pass bills the president has promised to sign. Until then, they deserve as much criticism and blame as Obama for impeding the long march to equality.
