Does that mean that I'm going to say no to every abortion reason? No. There's three cases where I say it's up to the mother - rape, incest, or severe danger to her. Does this mean I condone it? No. It means I'll respect her decision and support her, if she decided to have an abortion for one of those three cases.
You say that you would respect the decision of a woman who was raped to have an abortion. She didn't choose to be raped, so even though you don't agree with it you would still respect her choice to have it aborted.

That thought is a pro-choice thought. You think that it's acceptable for a woman to choose an abortion if it's under one of those three circumstances.

However if you are pro-life you are choosing to make abortions illegal, meaning that a woman who was raped would not be able to chose to abort the child.

That is why people are saying abortion is not black and white. Pro choice isn't saying "I think abortions are great and everyone should have one" Being pro choice means that you think a woman should have the right to choose if she wants to abort the child, it's not about you personally. It's totally possible to be stuck in the middle of both pro life and pro choice because of the situations you stated. That's why abortion isn't just a black and white situation.
