I don't side with either argument in this fight about when life starts. That being said, if I had to pick a mainstream title, it would be pro-choice.
A person has a right to choose what they want to do what their life. If they want to be pro-abortion, great. If they want to be anti-abortion, that's great too.
But the moment you start restricting the rights of others, you cross a very broad and obvious line that is basic human rights - did you know they existed? The UN made a charter of human rights.
http://www.un.org/en/documents/udhr/ - See Article 25.
Restricting a woman's right to abortion (ie; proper medical care) in this case is no different than Islamic Sharia law saying you have to cover a Christian woman's body. It is absurd to restrict basic human rights and this topic should not even be a discussion.
