Well of course she regards a wanted baby as a human living being. It is called emotions and if there is one thing, that makes people act illogical is emotion. Could you blame her? This also works the other way around, to convice yourself that the unborn is not a human being yet, if you don't want to put up with a child for whatever reason. (i.E not being able to support a child, having emotional traume...) Could you blame her?
All in all people are great to convince themself of anything and therefore such constructed cases shouldn't be used as dismissing those people and their positions as illogical, if you want to be taken seriously in a debate about a moral conflict.
