You're missing the point, Damo. Whether it's a child at that time or will become a child both anti-abortionists and pro-choicers acknowledge a birth may very well take place. That is the situation with which both should be dealing. What will be the ultimate best for the child.
Suppose one knew, for a certainty, if they bore a child that child would be captured as a young adult during a war and severely tortured for 10 years at which time the "child" would die. Would it be morally responsible to bring that child into the world?
It appears the incapacity for empathy rests with you. If a person knows they will not make a decent parent why would they subject their progeny to a situation like that? All one has to do is take a look at the world. How do we treat our ill and poor? How do we treat those young people who grew up in the ghetto and turned to crime? How do we treat those who have limited education due to having left a dysfunctional home at an early age?
If one knows they will not be a good parent, for whatever reason, it is the height if irresponsibility to bring offspring into the world. Do they correct the situation, prevent a later birth from taking place, or allow a process to continue which may very well result in a birth and subjecting their offspring to a life of misery?
People like to talk about convenience or whim when discussing abortion. Perhaps it's time to accurately refer to it as having empathy and taking responsibility.
