it's a grey area
people are at times declared as such for their ability to stand upright, speak and display mental development... I don't know how a newborn can display these traits.
edit:
the concept of abortion gets people all bothered because of everyones' ideas of murder... if it has yet to be born is it alive? once it's out is it a person? when do people decide to draw the line? and when does it start being a possible being and NOT a mess that can be easily discarded. You might say it's distinctly separate parts... but it seems there is a bit of fog around this subject matter.
