A baby is no more a part of a woman's body than you are a piece of furniture in your house just because you are inside it.
A baby is a being that has a certain state of dependency. The dependency lessens throughout childhood, but we don't abort 12-year-olds, do we? Then why should we kill 12-week olds? There is no material difference.
Can't believe abortion is being advocated on FR.
Mitt Romney, the de facto nominee of the Republican party, is pro-abortion. So, it's unsurprising that abortion is advocated in Republican and nominally conservative circles. I doubt that what is left of the pro-life plank in the Republican platform would survive a Romney presidency.
