In order of preference:
1. Married loving parents (one of each sex).
2. Loving single parent.
3. Loving parent with long-term gay partner.
4. Loving parent with many/changing partners.
5. Unloving parent(s).
6. No parents.
7. Aborted.
I don’t see why you’d have to go that far down the list. There are many, many mom-and-dad couples willing to adopt, who often cannot not do so because of financial constraints. Let churches, philanthropic foundations, nonprofit 501(c)(3)’s, or even counties and states subsidize adoption, and you don’t have to go past option #1. And the county and state can save caboodles of money from their failed temporary fostercare system.
Homosexuality is a disorder. Would you still include number 3 if it were instead, “loving parent with long-term alcoholic partner”?
