False dilemma. There is no way to simply remove a fetus and let it mature artificially. SciFi speculation aside, in the here and now what you are arguing for is the retention of abortion for the convenience of the woman; as you state, women abort because they don't want to be pregnant. Well, once they become so, it's far too late to be deciding that. They have already passed up a range of options to prevent pregnancy in the vast majority of the cases.
I understand there is no way to dothis currently. I addressed that point when I talked about organs. Was that not sci fi speculation at one time too? Indeed it was.
WHy is it too late? Because you say so?
It seems that the reason to oppose abortion as it stands is life, Once again i will state I agree with that position.
If life is maintained, where then is the opposition? It seems that the reason would then change and become that an unborn must remain and be carried to term where it began.
Then one must admit that is the true goal now. Fine if it is, but it should be admitted.
