To me there is no difference between the fetus and the newborn baby other than its age. Both are totally dependent on another human for life. And neither can exist without living through the formative stage in which they exist at any given time. Surely you understand the difference between a living being, full of potential, and a corpse? And, in my opinion, to not understand that the unborn baby, at any stage of his/her development, is a human life is to result in the attitude expressed by GEIxBattleRifle up there who seems to think eight billion people is sufficient and therefore life is expendable.
Such leads to forced abortion, forced sterilization, restricting couples to one child, etc. as we see in China today, or other cultures who see human life as expendable for the common good. Next we could be putting the aged out to die as the Native Americans once did, or destroying the 'lesser humans' as Hitler once did and to some extent slave-owning America once did, or committing general genocide of certain people as the Romans once did.
I want America to be better than that and to be a culture of life, not expediency.
