Interesting question, I happen to be male, so obviously my thoughts have no bearing on women who choose abortion, but I will state my thoughts anyway.
Women who are pro life bring stark reality into a situation that is difficult for women, who find themselves pregnant unwillingly, do they kill their baby, or do they value the life which (no matter HOW it was conceived) is a human life, a potential world leader, a potential astro physicist, but of course also a potential criminal.
Whilst I agree with much of what Aime states, because her points are valid, I doubt that all of the 40 million plus lives that have been taken (legally) were as a result of those conditions.
My main contention with abortion is that statistically it resembles eugenics, indeed it's origins were in eugenics, and most abortions are carried out on black women, which may concur with some of Aimes points in any case, but is either a dreadful statement on black people, or indicates a targeted social group, neither of which are acceptable situations in a western society.
So to conclude, yes there should be the possibility of abortion, in set circumstances, which should be determined and set in law, to cover situations like Aime set out, but equally, there should not be abortion on demand simply because people cannot be bothered to have a child.
The aborted human life is a life, if I kill a pregnant woman I would be charged with a double homicide, so in that instance, the law recognizes the truth.
By the way, my mother gave birth to me in circumstance that could have resulted in our deaths, despite being advised to abort me.
So yes I am slightly biased, and delighted that she chose for my life to have value.
