In this old post, Rosemary Esmay points out that John Kerry is pro-abortion is spite of his belief that life starts at conception. As I understand his comments Kerry believes that, while life starts at conception, personhood starts at birth. This is not a principled, spiritual stand. It contradicts Catholic belief, which is that both life and personhood start at conception. Dad the Catholic Democrat marches against abortion every year, and I the Protestant Republican often stand with him, so I know there are pro-life Democrats. I think of all the Quakers, including those elected to office, who stood strong against slavery, risking their own lives running the Underground Railroad. Where is the principled sacrifice in Kerry's stance?
One difference between Bush and Kerry is that Bush clearly believes in God and wants to act on his beliefs. If Kerry didn't show up at Mass once a week I'd have no reason to believe that he is a Christian.
In the comments on Rose's site I try to get an abortion supporter (who thinks he's conflicted, but won't make one move against abortion, because he considers it a right) to discuss personhood. He dodges questions on the subject for the entire thread. I suppose if one admits that Africans are persons it makes owning them easier, but if they aren't persons a slavery supporter might be forced to change his mind. Better not to talk or think about it.
