So of those that survive, most of them either have no disability or have something mild like a "squint". And for this, they must die?
I don't remember where I saw the stat, but in an astonishing number of the partial-birth abortions that are performed because the child is deformed, the horrible deformity is a cleft palate.
I can't imagine wanting the child less because of the cleft palate, but there are people who'll kill a kid over one and in a particularly torturous way.
