The problem I see is that if one believes that an unborn baby is just that, an actual baby in the process of maturing, it's really no great leap whatsoever to think that baby has every bit as much right to protection as one that is being held in it's mother's arms after birth. From this point of view the "decision" to kill one is little different than deciding to kill the other. This rather muddles the "government intervention" criticism since, at least by those that subscribe to the above definition of a living baby, it's no more of an intervention than legally preventing a mother from dumping her newborn in the trash because she felt it was her right to do so.
BUT
Lots of people do not subscribe to the above definition of what constitutes an actual "baby" and that's when things get hairy. I suppose what the OP is trying to get at is you don't (or shouldn't) get to cherry pick. For instance, if one is "pro-choice" it could look a little funny if you find yourself joyfully posting sonograms images of your "baby" on Facebook.
Frankly, I don't know how this one will ever get decided to everyone's satisfaction.
