I truly am sorry for your own fertility and health concerns and think it's wonderful that you would be prepared to open to your home and heart to children other women carried, biologically. And I wish more people were like you. Many more. But realities are not so simple for everyone.
This is a difficult subject for me to decide on, truth be told. For me, personally, it would be difficult if not impossible for me to consider abortion as a choice. But I still don't think the state has the right to police women's bodies ... especially since it does fuck all to help them or the kids it forces them to carry.
