This is more of a philosophical question than a genuine "I don't know" question (if that makes sense).
I was thinking about it just now after talking about the subject with a friend of mine, and I get why people would want to grow a baby once in a while, but why is it that some people feel compelled to make other people grow theirs? It's no good for the potential baby to have parents that aren't capable or willing to take care of it, and overpopulation is a pretty big deal these days, so having an increased amount of messed up, unhappy people is not a good thing (especially not if they're poor because of their parents' dropping out of school or not being able to pay all the bills as a result of their birth).
We were also on the subject of pregnancies as a result of rape. It's like, if you had been impregnated (against your will) by a facehugger (xenomorph subspecies, clings to your face and dumps it's load in your mouth), wouldn't you want to get that thing out of you before it grows in size and makes it's own way out of you?
I get why people may not want to abort their own fetuses, but what's up with forcing others to keep theirs?
