You can lower your pitch forks.

How do you even reach that conclusion based on that sentence? Your quote talks about equivalency, you interpret this as infanticide is ok. Those are two vastly different things?
> […] Newborn human babies have no sense of their own existence over time. So killing a newborn baby is never equivalent to killing a person, that is, a being who wants to go on living. That doesn’t mean that it is not almost always a terrible thing to do. It is, but that is because most infants are loved and cherished by their parents, and to kill an infant is usually to do a great wrong to her or his parents.
> Sometimes, perhaps because the baby has a serious disability, parents think it better that their newborn infant should die. Many doctors will accept their wishes, to the extent of not giving the baby life-supporting medical treatment. That will often ensure that the baby dies. My view is different from this, but only to the extent that if a decision is taken, by the parents and doctors, that it is better that a baby should die, I believe it should be possible to carry out that decision, not only by withholding or withdrawing life-support — which can lead to the baby dying slowly from dehydration or from an infection — but also by taking active steps to end the baby’s life swiftly and humanely.

Do not most people nowadays consider a post-birth entity with the DNA of homo sapiens a person of particular sub-type "infant" (as classified by age)? Singer does not classify them as a person from what I've read.
