Quote: D.B. Hart

 “Abortion is largely accepted even for reasons that do not have anything to do with the fetus' health. By showing that (1) both fetuses and newborns do not have the same moral status as actual persons, (2) the fact that both are potential persons is morally irrelevant and (3) adoption is not always in the best interest of actual people, the authors argue that what we call 'after-birth abortion' (killing a newborn) should be permissible in all the cases where abortion is, including cases where the newborn is not disabled.”

Abstract from "After-birth abortion: why should the baby live?" by Alberto Giubilini and Francesca Minerva

“... the autistic or Down syndrome or otherwise disabled child, for instance, for whom the world can remain a perpetual perplexity, which can too often cause pain but perhaps only vaguely and fleetingly charm or delight; the derelict or wretched or broken man or woman who has wasted his or her life away; the homeless, the utterly impoverished, the diseased, the mentally ill, the physically disabled; exiles, refugees, fugitives; even criminals and reprobates. To reject, turn away from, or kill any or all of them would be, in a very real sense, the most purely practical of impulses. To be able, however , to see in them not only something of worth but indeed something potentially godlike, to be cherished and adored, is the rarest and most ennoblingly unrealistic capacity ever bred within human souls.
