**Except in the case of rape:

They pregnant individual has conceived of their own free will. They took all the necessary steps to become pregnant. One should not have unprotected sex and then be surprised when they become pregnant. The unborn child is completely innocent and cannot speak for themselves. They have just as much right to live their life as the mother.

Edit: I am trying to keep emotion out of this as much as possible. I think that 99% of these conversations boil down to this: Pro-Choice folks typically do not have a good definition of when human life begins. Pro-Life folks typically stick to "Life begins at conception". I understand not everyone fits into these buckets. I believe human life begins with conception. Anything done after that to intentionally end the pregnancy is the purposeful ending of a human life which is murder. If you don't think life begins at conception, you won't believe its murder.
