I am pro choice as you know, but you mischaracterize the arguments for those who are anti -abortion.   

I can't speak for every motive, but I know some of these people and they love and protect every child in their community.  They also serve as foster homes for single pregnant women.   These are good people with good hearts, at least most.    

At my wife's funeral, my slide show of memories called my children Miracle One and Miracle Two.    We did not think Jana could have children (married 10 years to another person without using birth control), they seemed a miracle to me.

Now maybe it doesn't make any sense on the academic side, but for those of us present at birth, it is an overwhelming and special emotional experience.   With Jana thinking she was infertile, you can't imagine the joy it brought her to have our daughters.

Those kinds of experience can make it very hard to empathize with people who seem to treat pregnancy like a disease.
