The abortion rights group are interesting! You cannot limit abortions in any way according to many of them...up to and including killing viable babies. If you have ANY limits, it's the slippery slope. They prize a "constitutional right to privacy" that is nowhere in the Constitution. HOWEVER they will fight to the death to limit gun ownership. No slippery slopes in sight when it comes to a right that is explicity in the Constitution. And to those who say the founding fathers could not have foreseen the weapons we would now have--they were a pretty smart bunch, and they knew advancements would be made.
