I don't know of any instances of woman wanting to get an abortion after actually choosing the be pregnant unless there are medical reasons.
Women who get an abortion (not for medical reasons) are women who are pregnant against their will. And who thus did not choose to become pregnant.
Also, I'ld like you to clarify something...
Does that mean that you are okay with rape victims getting an abortion?
Certainly you can at least agree that rape victims at no point chose to even only "expose" themselves to a risque of getting pregnant, right? ...Right?
Because if you feel like they can't have an abortion either.... then clearly this "choice" isn't your actual argument and just a smokescreen.
Sorry if I misrepresent you if that is the case though.
But in other threads here, people have been using this "choice" argument as well and when rape was brought up.... well.... their responses weren't very nice.
