First of all, I am not saying that their life should be perfect since that is not achievable
What I am saying is that if society forces a mother to give birth to a child she is not prepared for than that society has acquired the responsibility to help and nurture that child due to its actions forced on the mother. If society does not help, it is helping to condemn that child to circumstances, beyond its control, that will serve to harm the child. If you fight for prohibition of abortion and do not help clean up the mess you created than you are evading your responsibility.
I personally do believe an unhappy life is worse than death. I have not proposed that I can make that decision for anyone, except me. This (to me) has nothing to do with the topic of unborn children because they are not yet completely alive. Because people and fetuses are not the same thing. I do not believe that this side track we went on really matters. You can call my terminology (fetus) dehumanizing all you want. However, I have seen ultrasound pictures of my own children, I have seen many photos of unborn babies in all stages of development and I still do not feel that they are completely alive when I look the whole picture. So this little side thing we went on is completely off track and has nothing to do with the real discussion at hand. My mistake and where I let this go to a tangent is that I got distracted by your hypothetical.
For me this is two completely different subjects and you seem to want to mingle them when they should not be. If you want to talk about unborn babies, we will go with the first paragraph. If you want to talk about people, we will go with the second, however I will completely change my argument because child does have a right to life once it is born.
However, I must thank you. I have learned something through this post. That is if I accept any my debate partner's assumptions that I disagree, I can easily lose control of where I am going and off on some tangent that has little to do with the original topic. After reviewing our posts, I have realized this and I thank you for helping me be a better poster.
