The California Supreme Court has blessed our family.

Our daughter, Elly, married her partner, Janelle, in San Francisco in 2004. But until the court ruled on May 15 that their union was constitutional, Elly did not have equal rights in America.

Opponents of gay marriage say it will be bad for families. So let's talk about families.

Early in the 20th century, Elly’s maternal great grandparents came to America from Russia to escape religious persecution. Her great grandfather vowed that instead of fighting for his life, he would work to save other people's lives, and he became a chiropractor. He moved his family to California because of the promise of universal college education.

A few years later, her paternal great grandparents came to California from Japan looking for a better life. Both families found an America where there was still lots of work to be done.

Racism was the rule of the land; those were the days of the shameful words "separate but equal.”

In the America of our grandparents' and parents' youth, we couldn't have married. It was in 1947 that interracial marriage was legalized in California.

We were lucky. Both our families embraced our marriage. Like our parents before us, we raised our daughter to value the whole human family, and equal rights for all. Years before we had any idea that our daughter was a bisexual, we were teaching her that marriage should be for everyone who wants it. She saw us working for that day.

Marriage equality for all is anything but an "attack" on marriage. It's a defense of the best that marriage and family can be.

All loving parents hope to be able to pass their values on to their children.

All loving parents hope to see their child secure in the love of their chosen partner in life, if the child chooses to marry. We know we won't be around forever, and we hope that when we're gone, someone who loves our child as much as we do will be there for her.

That means someone who can visit her in the hospital, tell the doctors what to do if she can't speak for herself, share their earnings and insurance and support each other in building financial security, share a name if they so choose, take equal responsibility for loving and educating both their children.

We were lucky enough to raise our daughter in an environment where being interracial was "no big deal.” Now we want to see our grandchildren able to grow up in a world where having two mommies or two daddies is just an everyday reality — no different than having one of each, and less important than whether to play baseball or soccer after school.

There will never be another day like that day in 2004 when our daughters got married. A dream we had barely dared to dream came true. We laughed and cried for joy, and hundreds of people laughed and cried around us. Our daughters' hands trembled as they exchanged rings, and our hands trembled, too.

And for Ken there will never be another birthday like May 15, 2008 — the day the dream that had been taken away from us was brought back to life.

We know the story isn't over. Already, people who are motivated more by fear than love have collected signatures for an anti-marriage constitutional amendment that may appear on California's ballot this November.

Yes, anti-marriage — because for no good reason, it would once again deny our daughter's dream, and stop many Californians who love each other from marrying each other.

But we will fight that misguided amendment with all our hearts and all our strength — for our children, and our grandchildren.

For our family, and all families.
