That's the big question, saying you don't approve of it doesn't mean you're going to abandon the child. I don't abandon my country the minute my government does something I disagree with, except if it's something very radical and big perhaps. Sure they wouldn't encourage the child and may not want it to invite a same sex boy- or girlfriend to their home but that is still different from abandoning the child, if they really love the child, their opinion may even sway or at least become less extreme, if one can say that it's extreme in the first place.
