I know you have a lot of replies but I wanted to offer another two cents.
We also do not, in any way, penalize adoption over having your own children. We consider it noble, even.
Further, decades of research into gay parenting has not shown that children of gay parents thrive on any emotional, social or scholastic parameters less than children of heterosexual parents.
In the US adoption is in no way tied to marriage. Gay adoption was already legal as well as surrogacy. Stopping gay marriage wouldn't stop gay adoption.It is hard for adopted children to be able to be cared for yet alone same sex couples. The lack of bonding is genuine care for a child is still a biological production of birthing.

Marriage as it stands in most industrialized first world nations is a government contract which merges wealth and decision making power between spouses so they can be taxed as a single entity. There is no stigma, government or social, here in the states against couples who are married but do not want children or couples who adopt.Marriage has been about procreation and the ensuring of society that a child will have proper uprearing and be of a benefit to society.
The government contract for tax purposes is a state matter. In the US there are several hundred rights and benefits provided through government marriage contracts.Marriage is not even a state matter, it is a civil matter and should remain so as a contractual affair. No government has a right to see who you marry and how you inseminate your spouse at night under any conditions.
I agree, churches shouldn't be forced to preform any marriage service. And they aren't. They can even refuse interracial marriages after Loving V Virginia lifted interracial marriage bans. But courtrooms, judges, marriage offices of the state, etc cannot.in such unions as well, it is a matter of the clergy and the religious tradition to decide if it is willing.
