I'm not going to discuss my personal feelings on the subject of abortion. My personal feelings are not relevant to anyone except myself.
Notice the key word there? It's personal. Personal choice. I neither need nor want my government limiting a woman's options based on some other person's moral dictates and religious beliefs. I want and need my government to support a woman's right to choose what is best for her.
I've seen a simple bumper sticker which concisely sums up my thoughts:
"Against Abortion? Then Don't Have One."
