Paul Katami and Jeff Zarillo, one of the two couples challenging the constitutionality of Proposition 8, California's gay marriage ban, say getting married wouldn't affect anyone else's marriage.

The Burbank, California couple together 12 years told Brenda Gazzar of L.A. Daily News that they would be in Washington on Monday, one of at least 2 opinion days left in the Supreme Court's term.

Katami and Zarillo said they remained hopeful that the court would strike down marriage bans throughout the nation.

“It would be a knee-buckling moment because it would be the first time in our history that the Supreme Court handed down a ruling that applies marriage to the [gay] community,” said Katami, 40.

“We just want to get married,” Katami added. “And that not only benefits our lives, it benefits our community. It doesn't really affect anyone else's [marriage].

Zarillo, 39, said that people understand the vocabulary of marriage, such as referring to his partner as his husband.
