John, your argument would be stronger if anybody were being forced to have abortions! The bottom line is that we do not know wether a person has a soul or not, yet you seem to want to define exactly when the soul takes residence!
You and I can afford to take a more reasoned stance to this problem as I strongly suspect WE will never have to make the choice ourselves. I do not know, so I will let those concerned make their own decisions and try not to be too critical of them for doing so!
