I personally do not approve of abortion. I'm not very religious and believe that you only get one chance at living. I support life wherever possible.
I'm also old enough to know that if abortion is outlawed, many women will try to remedy the situation themselves and out of desperation perform self-abortions. In which case even more will die. I remember that women did die before abortion became legal and I never want that to happen again.
For me it's not about the "right to choose" or "it's my body", etc. It's about the horror of back street abortionists. Abortions must remain safe, affordable, legal and accessible to women who want them.
