Pro-choice 100%. It has never made sense to me to legislate away someone else's choice. Keep your personal beliefs to yourself and don't have an abortion if you oppose, but your personal beliefs have nothing to do with my body and my fetus.
I'd say it's both a women's rights and a human rights issue. Secrets is right, the debate seems to usually gravitate towards where we draw the line. There are the fundamentalist nutters who oppose stem cell research and won't use birth control... yeah no. I think having a cutoff point is an okay compromise, but it should be a flexible thing in case there are complications involving the woman's life.
