I don't see why not. To many people, there is a big difference between killing an animal and killing a baby. Personally, I wouldn't do either.

Indeed, and further, plants are life as well, so they couldn't kill any plants either if we followed the logic being presented here. Even more, someone who is 'pro-choice' would have to be pro-choice on any possible choice. This is what happens when you take these one-issue labels and apply them literally to all possible issues.
