Ethicists say babies aren't persons and be killed morally

From The Telegraph comes this frightening news of a recently published article titled "After-birth abortion: Why should the baby live?":

The article, published in the Journal of Medical Ethics, says newborn babies are not “actual persons” and do not have a “moral right to life”. The academics also argue that parents should be able to have their baby killed if it turns out to be disabled when it is born.

This is nothing more than infanticide.

According to the authors of the study, newborns are simply "potential persons": "Both a fetus and a newborn certainly are human beings and potential persons, but neither is a ‘person’ in the sense of ‘subject of a moral right to life.’"

I wonder: Where will the final line be drawn by these so-called medical ethicists as to when a person is a person?  Others have attempted to make such a distinction before and I daresay it did not end well.  This not bode well for society.
