I'm Pro-Life... but with a lot of strings attached, and some of my reasons might be stupid, I don't know.
A fetus, to me, is life.
Pro-access to comprehensive sex education and pro-access to contraceptives, in my perfect world, everyone would have a wonderful and informative sexual education, and have free/cheap birth control available to them. This is how it was for me (unfortunately this isn't everywhere), at 15, I was able to get on birth control, without my parents knowledge, and it was free, they made this extremely well known throughout the school, they constantly had fliers and always attended the health fairs my school would have.
To me, as long as you made an attempt to not get pregnant, you should be allowed a choice. By being on birth control (even if you take it incorrectly), purchasing condoms, ect, then you have the choice to get an abortion should an accident happen. You were smart, you did the best you could, and something didn't work, but at least you tried.
Also, rape or similar circumstances are able to choose as well.
I know it would never work, though.
