One unspoken error in many of the comments is the assumption that the only women taking birth control are young single women, out boinking without any consideration of consequences. This is clearly false. Hell, even married Catholic women use The Pill. If you look at the familes of these pro-life advocates, you may find they have 2 or 3 children, not a dozen - Quiverfull excepted. They are most likely using The Pill or an IUD. This is entirely consistent, given the recent retirement of a 100% pro-life senator after wanting his mistress to have an abortion. It's important to stand behind your moral code - until it becomes problematic for you.

Next up - religious exemptions for vaccinations.
