The other day, in the real world, someone asked me what was the Church of Scientology's position on abortion.
I didn't have a ready answer because I don't think the Church has one. I've never heard it mentioned because it's one of those things that is up to the individual, and the Church doesn't interfere with individual choices in such things.
I would assume that staying out of this area is covered by the "Second Dynamic Rules" policy where L. Ron Hubbard says "It has never been any part of my plans to regulate or attempt to regulate the private lives of individuals." (I mentioned this policy recently in the post "Scientology and Homosexuality".)
So I guess the answer is: "It's up to the individual."
