As in: "Only God can administer life and death, so stop those abortions or we'll set on fire your clinic and kill the doctors".
Psychology can explain completely that behavior, however this is not the right place for such discussions.
It is pro innconcent life, not pro murderer life? Pro life and pro choice are just marketing terms. People who are pro-choice aren't pro not wearing a seat belt (well some may be, but it has nothing to do with the topic). It has to do with abortion and only abortion.
