Perhaps, and I am just speculating, the fact that you are in Scandinavia where pro-lifers have given up long ago with respect to swaying the mainstream affords you the luxury to discuss this topic philosophically?  Whereas in America the pro-lifers are in the process of attempting a coup on our government and therefore everyone, on both sides, is more concerned about winning in the court of public opinion, and er, in the Supreme Court, than ruminating on the essence of being or concerning themselves with proper reason and logic.

And even if they were, in order to have a philosophical debate on the subject, those participating should be versed familiar with the basic rules of the game, which they are not.  At some point, the statement "Cuz that's what I believe," came to pass as a valid proof here in America.  

I'm just saying that while your argument might be spot on, and I am inclined to think it is, I don't see it being an effective tool for protecting American women's rights from being steamrolled by the Christian Right.  That's all.  It seems that the most vocal on both sides have given up on tring to win "hearts and minds" and are just going for the hearts now...
