I'm not much concerned about 11 week old fetuses. I've said a bunch of times it's approximately weeks T-4 and forward to birth that are most troublesome, in thinking about abortion. No the concept of birth does not mean much more, in this context, than the concept of becoming two years old. It's a more spectacular milestone, but part of a larger process.
Compare a very late-term fetus to a vicious murderer, and the choice favoring the former seems so obvious as to defy the need for argument. Not pedantic at all.
