After-birth abortion: why should the baby live?

Wow, is this the result of the slippery slope argument that many people said was coming while others said that would never happen? After-birth abortion: why should the baby live? -- Giubilini and Minerva -- Journal of Medical Ethics:

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.
