Lets say you are driving down the street, and my father's elderly mother is slowly ambling across. My father sees that you aren't watching where you are going and don't see his mother, and so are bound to hit her at a high rate of speed with your car and kill her.
It would seem you support his right to "choose" to shoot you or not in order to save the life of his mother.
Hermann, you may have won at Teutoberger Wald, but that analogy doesn't hold water.
Would YOU choose to save the life of an unborn child over that of your own wife??
To argue that kind of position is like saying the Second Amendment gives me the right to build a nuclear bomb ni my backyard.
