I don't disagree with that conclusion. So how do you deal with all of it? You can legislate against same-sex couples adopting. How do you deal with divorced single parents and single parents by choice?

Yes, why not? They are not the best environment for a child to be raised.

Elimination of no-fault divorce would be a good start.
Inability of a birth mother to name a father would be met with NO public assistance of any kind. Best outcome in many instances would be for the mother to put the child up for adoption to a heterosexual married couple that would offer them a more stable household to grow.
