I can appreciate what you are trying to say about the abortion debate - I am certainly largely glad to live in a country that has an abortion policy that, although highly grey in definition, and very imprecise, avoids the way-out-there things that go on in some of your states, and the ferocious debate that trails sick issues such as partial birth abortions.
You are right to say;
At what point does it become a human being? That is the question.
Now the question has to be asked; when do you think a human life begins? And importantly, when do you think something that can be called a human being has its first day of its existence?
