Actually, the point is not very strong.
Consider the difference between a single-parent and a homosexual couple having children.
In the first instance, the woman or man has a kid the good old fashioned way, then for what ever reasons they are left on their own with one or more children. They have had these children, and as it stands, no authority has the right to take these children away unless they can prove that the parent is incapable of looking after them.
In the second instance, the second couple can't naturally have children, and in many cases needs some kind of third party to participate in order for it to be accomplished.
And that's the difference. The fact that in the first instance, the burden of proof is on the state, or the authority, because the child has already been born and is settled with one parent. In the second instance, the burden of proof rests on the couple trying to get a child, because the third party needs to know that the child will be safe.
As for adoption, like you point out in your thread, the issue is that there is the third party, the adoption agency. Theoretically, it wouldn't matter whether you're gay or a single parent; you'd have to jump through some serious hoops to prove yourself.
I'm not saying that the system of who has the burden of proof is the right way to do it, I'm just saying it's the way it is.
So the point about single parents as opposed to homosexual couples is pretty much invalid.
