When are you going to understand that you are not in control here, and never will be? You are never going to change the constitution to acknowledge unborn fetuses, you are never going to take control of womens' bodies, and you are never going to get abortion tossed out in a country as developed as the United States. In fact, even if by some grand deception you get the law changed, women are still going to have abortions. They always have and always will have control over that process.
You need to find a different pet project to occupy yourself with because you will never gain ground here with the kinds of arguments you put forth.
EDIT: I forgot to add. Up the street from me recently, for the first time in my life, I saw abortion protesters. They stationed themselves at one of the busiest intersections in the city and were wearing those giant, body-sized signs covering their front and back, with pictures of aborted fetuses and the usual trite little slogans. Every person protesting was 60+ years old.
I thought to myself... this is the face of the anti-choice movement. A bunch of backward, old, religious conservatives that haven't caught up with the times. Yes, there are young people against abortion, but ultimately, in the political spectrum, most of them fall on the pro-choice side because they are not willing to do anything about it. They acknowledge that they cannot control another person's wish to abort.
The face of the abortion movement is OLD. With each generation that passes, the right to abortion will be more and more secured.
