It is indeed the argument with the least scope. (It is a strong argument in that scope and not it does not assume to be the whole view. Rather it is an unvoiced perspective that can be inferred although I will point it out below)
I brought it up because it has a different take on Abortion than the other opinions being posted.
It points out that their is a conflict between the mother's right to her body and the child's right not be be let die.
The question is what circumstances cause the mother to lose this right. We know (if the argument is believed) that the mother retains this right in the case of rape. But the question becomes why and how the mother might lose this right in other circumstances.
My purpose was to present another perspective (I was informative not persuasive)
I am leaving rape alone, and let your argument stand for the time being, as I have told many people (although not in this forum) I believe rape and the mother dieing are the only 2 actual good reasons for having an abortion.
The mother loses that right when her physical life is put in danger, or the action that is a precursor to the baby coming (having sex) was not willful.
If I signed a contract with you that said
"You get my House for free, however, there is a 0.01% chance of you having to pay me 1,000,000 dollars within the first month."
9,999 people have all got the house, and havent had to pay after the first month. You decide to sign the contract, and you get the house. Now, sometime before the first month, as luck would have it, you have to pay 1,000,000 dollars. Should you be allowed to back out of the contract just because luck wasnt on your side?
