I agree...somewhat. i (mostly) agree about how you look at a fetus, but think about this: what would be better - for this fetus to have never been born, or for it to grow up in poverty as an unwanted and unloved, (and possibly burdensome) child to the parents. now im not syaing this is always the case, but there will be people with this situation. the reason why i say i mostly agree with your view of the unborn kid is that, under a certain "age," it cant feel, cant understand. theres a point where it can feel or react, but until then, it is as unconscious of it's being as anything. "I think, therefore I am." If something can't think, is it then not considered murder? and even then, other animals are killed, and they can think.
Also: In terms of "kid potential," a point that many people have brought up, theres many MANY possibilities of "unreached potential." another point about "unborn potential" is that, at least for girls, it starts being "wasted" around the age of 13. you cant argue that every bit of dna should be used.
but yeah. just adding on.
