There is nothing special about humans. If something is growing inside of my body, I can decide to remove it. Whether it is my kidney or a fetus is unimportant, if it is in my body, it is my decision on whether it gets to stay.
If its viable, I *might* be willing to grant that its death is gross negligence causing death. It is hard to imagine that there was not a better time to deal with it prior to the point of viability. There are plenty of people trying to adopt newborns, if you got that far, just go through with it. Furthermore, there are pills nowadays that will eject the contents of one's uterus early on much like sticking fingers down your throat ejects the contents of one's stomach. The problem is that the anti-choice crowd doesn't want society to have the choice that pill gives.
Eating meat is as much murder as abortion, I'd argue more actually. There is nothing morally special about a human, despite the question begging by religious zealots.
