I think some people are more careless than they should be with contraception because they know they've got abortion as a Plan B. If abortion was illegal as infanticide, people would have to make sure they don't fuck up the first time.

This experiment's been done. It continues to be done. What happens is that women still get pregnant, because contraception fails, because they are raped or coerced, because they're denied contraception, all sorts of other issues. Once pregnant, some women's circumstances change dramatically (from severe domestic violence to unexpected life upheavals of other kinds that require they focus their resources on the children they already have), they develop severe pregnancy complications, etc. Without safe abortion, these women don't shrug their shoulders and go "Oh well, happy baby-having time now!" They have unsafe abortions. As women have had since time immemorial. There is nothing new about any of this; I'm very surprised that you seem so very unfamiliar with the issues, preferring instead to cast all women seeking abortion in the "careless sophomores" mould, which is wildly inaccurate. Are you a college student, by any chance? Have you been pregnant?

I don't think anything justifies aborting a baby once a woman's already pregnant.

Get back to me if I ever get pregnant again, eh? There's a good chance I would experience life-threatening complications, like last time, and could need an abortion, because I want to be around to see my son grow up.

I'm rabidly pro-women's rights, but only if no one is killed in the process.

From what I've read of you here, this should read "only if no embryo or fetus is killed in the process". You haven't shown any signs of giving a shit about women being injured or killed.
