Well, what is your "grasp" of pro-life? What does it mean to you?
Pro-life is pro-life.
What "pro-life" DOESN'T MEAN to me is demanding a person's life be sustained or prolonged under any and all conditions, however horrendous or hopeless and without regard for their personal choice, and right to make end of life decisions.
(or a family member's decisions when they are determined responsible in such cases.)
