A barely developed fetus has no understanding of emotion nor does it have any sort of determined future. "Killing" a fetus is pretty much the same as killing a plant. If someone is raped or does not want to have a child, they should have full freedom to get rid of the fetus.
That "fetus" is just as Human as you are, the only difference between you and he/she is that you've grown up more. They are genetically fully Human, they have just as much potential as you for a future, and their life is just as valuable as yours and mine is. If someone is less developed than you mentally, physically or emotionally, does that make it okay to kill them off?
See, this is exactly what I was talking about in my post you responded to. I'm willing to bet you wouldn't support the practice of concentration camps because they wrongly treat the people exterminated there as subhuman in order to justify killing them, but you're willing to say the exact same thing about innocent children; you refer to them as subhuman, plants, parasites, "just a fetus", so that it becomes acceptable to dispose of them as if they were garbage.
