First off: where do you get the idea that Republicans would ban all abortions? Typical scare tactics and an insult to the intelligence of any thinking person.
Second: you are certainly entitled to your opinion, even if it is half-baked and without merit.
Third: certainly women should have control of their own bodies, and be entitled to free choice. In MY opinion, that choice was made when choosing to use no birth control. Once a life is conceived (again, in MY opinion) that woman is no longer choosing for herself.
I understand that there are no absolutes in life; there needs to be room for exceptions and extraordinary circumstances. Nevertheless, it's my belief that if a woman can choose to have unprotected sex and conceives a child, she (and the father, of course) have created a responsibility, not an option.
Just my opinion, and one I'm quite sure that would never get traction in today's society.
