It's not homophobic. You are homophobic, and since you can't win the argument that allowing same-sex couples to adopt children provides a better option for those children than being in the foster system, you have to propose that we fix the foster system. The problem is that it's not that easy to do... You can make adoption easier by simply not allowing biological parents to make later claims on their children. It's a ridiculous loophole, and should not exist. But even so, including foreign children, there are not NEARLY enough adoptions in this country to empty the foster system. Even if you include same-sex couples who want to adopt. So you're really still not accounting, numerically, for the fact that children would be better off with same-sex parents than foster parents.
