What you suggest is ridiculous though. You seem to be saying that if you do something that results in an outcome you didn't plan for you have no right to mitigate the effects and simply have to carry them around for the rest of your life. That's like saying the person who took the 1% chance of getting hit by lightning shouldn't get a skin graft for any burns they got since "They knew the risk"
"Rest of your life"? Try several months. This isn't something that an unwilling recipient has to deal with for the rest of her life. You can carry the baby to term, give birth, put it up for adoption into a family that actually wants it, and never even think about it again if that's your wish. Don't want to have even a remote chance of that? Then
don't have vaginal sex. Really, I don't know any other way to convey that sentiment more clearly.
Putting aside issues such as financial or societal pressure, when it comes down to a simple "I don't want to" opinion, I think it's just one massive case of people wanting to have their cake and eat it too. You know there's a tiny risk of pregnancy while having sex even if you use protection, but you do it anyway. And if you wind up falling in that 1%, you just snuff that entity out, just because it would inconvenience you. There's a staggering simple alternative, one that still allows one to think with one's pants, but no, that'd be far too easy, wouldn't it? Instead, let's build up a big international abortion industry, just so we can keep screwing in the coochie. Wonderful, humanity.
