In a world that seriously doesn't require any more tiny humans, let alone ones that don't have a receptive family to raise and nurture them so they won't add to the problems we already have, I don't think raising an unwanted child is legitimate in any sense at all.

We have more than enough children and adults that the world doesn't care for sufficiently, that die, kill each other or take their own lives - this idea of lavishing such great importance on something that only exists in potentia is crazy-talk to me.
