Why do people believe that pro life and pro choice are two sides of the same coin?

Question

PLEASE DO NOT USE THIS QUESTION TO DEBATE ABORTION.

This question is about the terms outlined above. With Pro Life being a viewpoint based on the value of human life beginning at conception, and Pro Choice being a viewpoint based on the freedom to have a medical procedure, have the two sides completely missed their mark when arguing with each other?

Answer 1

The Pro-life says that the life has started has a right and a choice too while Pro-choice says that the newly started life does not have a right and choice, it's still up to the one carrying the life.

How can it be anything but the opposites of each other? I've tried to figure that out but I'm stumped. Perhaps you should have explained it with more detail so that we can understand how you think?
