oh, and @Krellin's post regarding murder in Detroit.
The arguement wasn't that it's going to happen anyway so let's legalize it, the position being taken was, if we make this illegal women who choose to exercise their rights will die needlessly.
You are in favour or killing women who, due to circumstances whether family, religious or economic, would choose to have an abortion regardless of the law.
On the other hand, the solution to both your comment about Detroit's murders and laws regarding Abortion is still to do whatever we can, as a society, to help each other. To prevent the need for abortions, and the circumstances whereby individuals have so little to lose (in terms of societal status) and so much to gain (in terms of street-cred) by killing one and other.
The simplification of 'detroit criminals = evil' is a flawed misunderstanding of reality. It can be seen that humans will act to make themselves feel good and worthwhile, and when a society offers no other options or role-models young males will engage in violent behaviour and young females will engage in sexual behaviour.
They do this to impress their peers, to prove they are grown ups and to feel good. They will earn status among their peers which would have been very well understood in a pre-historic human culture.
