Here's something else I can't normally say in public:

Infants are not people because they do not have significant mental capacities. They should be given the same moral status as, say, dogs. It's acceptable to euthanize one's pet dog for many reasons, so it should be okay to kill a newborn for similar reasons.

In other words, the right to an abortion shouldn't end after the baby is born. Infants probably become more like people than like dogs some time around two years of age, so it should be acceptable to euthanize any infant less than two years old under any circumstances in which it would be acceptable to euthanize a dog.
