What the NY abortion law does and does not change

If we can coolly accept the deliberate destruction of a baby who is not expected to live for more than a few days, what’s to prevent the killing of a child who would only last a few months, or a few years? Why should we flinch at suggestions that a handicapped child or an elderly person should be taken away for a sterile “medically necessary” execution? We are no longer on a slippery slope; we’ve arrived at the bottom.
