I agree with that totally. I'm so guilty of this very thing.
However it's difficult for me to simply justify and rationalize the act of abortion -- even though it's someone else's choice -- because the fact is, there's a newly created life who should also have a choice in the matter.
Pro-lifers feel abortion is wrong just as many on the left feel that capital punishment is wrong, thus you generally hear lots of verbal protests from both sides. We pro-lifers often get accused of "judging" people, while anti-capital punishment folks deem themselves as "courageous."
