That's it. War and capital punishment are not always wrong. Abortion is always evil. it's those moral absolutes they have difficulty with.
The left either doesn't see, or doesn't want to see, that there's a difference between abortion and capitol punishment. To them, liberating 24 million people in Iraq from tyranny is bad, but starving a woman to death is A-OK! I gave up trying to figure out liberals years ago. They just are too illogical.
