Austin Ivereigh on "The Letter"

The arguments for allowing abortion under very limited circumstances are precisely the same as for allowing abortion under broad circumstances. Legalising abortion out of compassion for the mother’s pain — which is what motivates Professor Beattie — implies, at once, rendering the unborn life a lesser being. First the law strips it of rights, then it is able to be killed.
Once the law declares that the baby of a woman who has been raped, or a disabled baby, is not a life worth defending or saving, it crosses that threshold.If the law does not declare that life worth living under those circumstances, it cannot logically declare it worth living under other circumstances. A life is recognised as such in law, or it is not.Even without religion to teach us that every life, however conceived, is a reflection of the divine, legally and philosophically this has always been an either-or question.

Nails it.
But Eccles still has the best line.

Herod was pro-life, since he only killed people under 2 years of age.
