So according to you if a person isn't a child's biological parent then the couple can't get married...Do you realize how ridiculous you are? You're telling all people who have been divorced and have kids that they can never get married again. You're also telling infertile people that they can never get married or adopt children to have a family..
Nope, listen carefully:
1. A state's interest in marriage is solely for the benefit of children that will likely come to them.
2. As such a state's interest in marriage is incentivizing a home environment that is best for the child[ren] that will LIKELY come to it. This isn't a hard and firm qualification program. Marriage is an INCENTIVIZED institution that rewards the best environment for children. That best environment since the dawn of prehistory, coupled with a Mt. Everest of studies and hard data is a home where both blood parents are in it. Failing that the state finds a close second is two adult people of opposite genders that prepare the child emotionally and psychologically best to find his or her own place in the world and to learn to interact with BOTH genders and appreciate BOTH genders on a daily basis for their unique place in the world and input.. they see this also reflected in themselves.
Now then...
3. Gay marriage guarantees that one of the two blood parents of any children in it will be missing one of their blood parents 100% of the time. Likewise missing the complimentary gender vital for balanced formation and self esteem 100% of the time. How this can go haywire for a child is best illustrated in the OP here: with poor little Thomas Lobel of Mental-Illness-Institutionalizedville (California)

4. So like single parenthood, gay marriage promises children no other situation but missing one of their blood parents. Worse, it also guarantees a vital role model for the proper balanced mental formation of a child....missing 100% of the time. So as far as the state is concerned, gay marriage is as valuable to a child's rounded formation as single parenthood. And the case of Thomas Lobel is a compelling argument that it is far far worse even than that.
5. So, until gays can convince child protective specialists, the state welfare agencies, juries and judges and most importantly the registered voters of a state that children will fare just as well missing one of their blood parents and the complimentary gender 100% of time in these new and untried "child rearing experiments", we ought not advance children into them with incentives as lab rats. Children are not lab rats for society to **** up a couple of generations and then later say "oh, you know all that evidence we had back then that this probably wasn't a good idea....we should've erred on the side of the children..."
6. As for divorce, no state wants divorce where both blood parents are in the home. That's why custody arrangments after divorce are almost like the parents are together. The parents are cautioned to not speak ill of each other as the child visits and if they do the courts penalize them. So they effectively are quasi married until the children reach adulthood. They just live in separate homes. This doesn't conflict wiht the state's position as incentivizers of marriage for children's sake. Divorce is the lesser of two evils. The second being children forced to be in a home where their parents are bitterly battling and have grown too distantly apart. So, reluctantly and with stringent conditions enforced to continue to insure the welfare of the kids...and access ongoing to both blood parents, the state grants divorce for their best wellbeing.
7. As for adoption, two people of the opposite gender do not interfere with the best arrangement for kids in the home. So they are allowed. And if children come into their home from adoption, there still is the arrangement of complimentary genders for the child's best mental formation as s/he grows up. So there is no conflict.
Couples don't have to prove they are fertile to qualify, only that they are structured as a fertile couple. This is the blood parent thing and there's no escaping that two gay people will never pan out as either two blood parents to the child or the vital complimentary genders for the children's self esteem.
