Like I said, perhaps there are not enough "straight" foster homes. Would you rather a child be in a dangerous situation with biologial parents or in a same sex home where the child is safe? It's a no brainer. I don't think it's experimental at all.
I know a family of 2 lesbians and a child. I asked one day, rather boldly, now that Jessie was in daycare and was more active with children who had a mommy and a daddy, how did they explain their living situation to her? What they said made perfect sense to me. They told Jessie that some families have a mommy and a daddy, some families only have a mommy, some only have a daddy, some have 2 mommies and some have 2 daddies...and all of them love their children just the same. What else needs to be said?
