But the situation isnt like you describe it. The gay parents in this case impregnate a surogate mother that carries the baby for them. Withouth the gay parents there would be no child, so the chooise is in reality.
1. A baby is born to the world that will be raised by two men.
2. No baby is born.
The third option, a baby beeing born and raised by two parents of different sex doesnt even enter the picture. So then the real question is, do you think its better that the baby isnt brought to this world rather than having it raised by two men?
