Admittedly, the foster care and adoption systems are far from ideal, but at least they're there. The state can and does compel the people who did the procreating to support the upbringing of the children. Sometimes they can't or won't, but still, it's a system and a legitimate function of government. The marriage license is a way of saying "These people are responsible for that kid." Not perfect, but extremely useful all the same.
Which means, of course, that formal marriages between gay people are necessary. Not just desirable; necessary. Gay people have kids too, increasingly so, and those kids require equal protection under the law. To create two classes of marriage is to create two classes of children, and that is both morally and legally unacceptable.

And you (3) people - here's a summer vacation plan for you. Come to the Bay Area. (Hint: Bring layers. We get fog. Better yet, come in October.) Gay families are thick on the ground and would be happy to speak with you. See their well-adjusted children except for Jason! Watch them shop for groceries just like human beings! Some of them - you're going to love this - even go to church and pray to God and sing hosannas, secure in the belief that the God of their choosing embraces all people in his compassionate glory.
Other gays and lesbians, not so much. But they all agree on spaghetti, and isn't that the important thing? If you can get spaghetti down, you can be married. Let's make that the test.
