"Pro life" is a feel good yet entirely inaccurate euphemism for "anti choice." One can find something unethical yet not want to ban other people from doing it. For example, I find both meat eating and religion unethical but I don't wish to stop others from eating meat or going to church.

Later? The majority of women who have abortions are already mothers. [1]
