Defending the rights of Married People...

means repealing DOMA.

Because laws have consequences that affect real people:

EDITH "EDIE" WINDSOR and Thea Spyer were together for 44 years and legally married since 2007. They lived in New York, which recognizes same-sex marriage. But none of that mattered when Ms. Spyer died at 77 in 2009 after a decades-long struggle with multiple sclerosis.

Ms. Windsor, now 81, was treated like a stranger to Ms. Spyer because of the federal Defense of Marriage Act (DOMA), which recognizes only marriages between one man and one woman. She was forced to pay ... federal inheritance taxes.

Gerald V. Passaro II and Thomas M. Buckholz had been a couple for 13 years when they were married in 2008 in Connecticut, which legally blesses such relationships. Mr. Buckholz had worked for 20 years for Bayer Corp., which extends certain benefits to domestic partners; he was also vested in the company's pension plan. But when he died in 2009, Mr. Passaro was denied benefits for surviving spouses. Because federal law governs the pension plan, DOMA applies.
...
This month, Ms. Windsor filed a lawsuit in New York challenging the constitutionality of DOMA. Mr. Passaro is one of the plaintiffs in a separate lawsuit in Connecticut.
...
This year, a Massachusetts judge ruled that DOMA violated the equal-protection rights of same-sex married couples. Ms. Windsor and Mr. Passaro offer convincing arguments for why the jurists overseeing their respective cases should reach the same result.
