This argument is obtuse. The contradiction is that it is considered a matter of personal responsibility as soon as a newly born infant suffers from abuse, malnourishment, poverty, and/or neglect, but before birth it is a matter of moral principle that the child, however unwanted, is born.

But child abuse and neglect are already illegal, and we already have programs like WIC.

Where did I say anything about the legality of child abuse and neglect?

If that's not what you meant, then I don't understand what contradiction you're trying to point out.

What is allowing the mother to die because abortion is against the law but "post birth" abortion? Or do you think that the lives of women already born should take a back seat to the potential life of a fetus?

When is letting the mother die the only way to save her child's life?

None of those states want to make post-birth infanticide legal.
