11 pages in, probably a bit late to the game. Nonetheless:
I am pro-choice, and I am pro-choice for the following reason:
I am not a woman, I will never be a woman. As such, I will never fall pregnant. As such, I will never understand what it is like to be pregnant. In particular, I will not understand what it is like to be pregnant with a child you either do not want, or simply cannot care for.
Therefore, given that I will never understand these things, I feel I have simply NO RIGHT to tell women what they should do with their foetuses.
I have no right to say "keep the baby and raise it anyway, your fault for having sex"
I have no right to say "give birth the baby and then put it up for adoption - it's not as if you'll love it, right?"
I have no right to say "pregnant through rape eh? Bad luck there missie, now push!"
Abortion is not my decision, it is the decision of a pregnant woman.
