we don't get to kill for the sake of convenience. Even if you're inconvenienced for a full 9 months.
I have neighbors I absolutely loathe. Their yard overlooks my yard, and so they see everything that goes on here and apparently they don't watch tv, but spend all their waking hours obsessing over what I'm doing....whether I'm maintaining the yard to their specifications, picking up after the dogs, maintaining adequate silence so the sick old man can sleep all hours of the day. Do I think my life would be better if they just died and went away? HELL YEAH. Do I get to kill them? Nope.
This is a false analogy, and your argument fails accordingly.
Abortion is not murder, where killing your elderly neighbors clearly is. There is also no evidence that abortion is motivated solely by a desire for convenience.
Over 95% of abortions are NOT to save teh life of the mother, or for rape, or becaues of some birth defect.
They are using abortion as a form of birth control in the vast majority of cases. And what does that do when you can use abortion as birth control? It enables poor decision making. And in this case someone ELSE has to pay the price, and with their lives.
