"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.

Lots of people have an abortion and then later have children.

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