Good gravy, what a bigoted complaint. Simply deplorable. I hope the mother in this case still understands that she is the child's mother, no matter what the screwup at the fertility doc's.
I can see them suing for some kind of damages for the malpractice, but complaining that the infant is "not even the same race, nationality, color ... as they are" is awful. Many, many adopted children have a similar circumstance, and their adoptive parents are no less their parents because of it.
Makes me wonder if that child is safe and cared for. She obviously isn't loved.
