Brian Brown, president of the National Organization for Marriage (NOM), has vowed to “roll back gay marriage” wherever it exits.

Brown made his comments in an interview with The New York Times, adding that “Ultimately, as Lincoln said, we can't have a country half slave and half free.”

NOM, a large contributor to passage of Proposition 8, which for nearly five years trumped a California Supreme Court decision legalizing such unions in the state, hasn't been much on the winning side in recent months, losing 10 battles since November.

In an appearance Sunday on This Week, Brown called the Ninth Circuit Court of Appeals' decision to lift its hold on a lower court's ruling invalidating Proposition 8 part of a pattern of “lawlessness.”

“The rule of law is harmed and all those millions of voters in the state of California who stood up and said, 'We know the truth about marriage. We know that marriage is the union of a man and a woman.' They are harmed when the courts are used to say they don't have a right to be represented. And that's what the court did. … Is it an American value to deprive those people in California who stood up and voted to protect marriage as the union of a man and a woman from their right to be heard?”

“The court … did not create a right out of thin air to redefine marriage throughout this country. What it did do is rob the proponents of Proposition 8 after they had seen utter lawlessness with Governor Brown and the attorney general refusing to defend the law.” (The video is embedded on this page.

On the show's roundtable, Delaware Representative Donna Edwards, a Democrat, disagreed, suggesting that the rulings created a foundation for the court to later affirm gay couples' right to marriage.

“I think it's almost three strikes and you're out: DOMA, Prop 8 and the next to go are the state bans,” Edwards said.
