People on both sides of this issue have said it is vital to overcome our emotions and think and act rationally. But let us not forget that some of us see abortion as nothing less than the murder of a human being. You will never convice us that we should overlook, trivialize, or legalize it.
I think part of the problem is the (often deliberate) use of emotionally-charged terms. Emotion is poison to any rational debate.
Calling abortion "murder" is one such instance. Murder is
wrongful killing; it is not murder when you kill someone in self-defense, or by non-negligent accident.
And you yourself acknowledge that abortion may not always be wrongful, when you state that you are "undecided/ambivalent on the aborting of a two week old fertilized egg." If you truly believe it's murder, you should not be ambivalent; conversely, if you are ambivalent, you perforce have some doubts about whether it's murder.
Something I think almost all of us can agree on is that at some point, abortion becomes wrongful. I ran a poll on this some months back that bore me out on this; the problem was, we were all over the map on
when it becomes wrongful.
Drawing that sharp, bright line between permissible killing and wrongful killing is the ugly part. I think the factor that weighs heaviest in most of our deciding that question is the amount of intelligence involved.
Nobody feels remorse when they yank a carrot out of the ground and throw it in the cookpot. The carrot has no intelligence. Very few of us feel remorse for the tuna that's going into our sandwich. Moving up the intelligence scale, however, we start to think about it. Significant numbers of people who would eat fish won't eat pigs or cattle. Why? What distinguishes a pig sitting on your plate from a fish? Intelligence. Why don't we eat dolphins? They're pretty easy to find, easy to breed, and I'm sure very nutritious. Is it because Flipper is one of the closest animals to us on the intelligence scale?
Meanwhile, we don't feel bad when grandpa dies after weeks in a coma or years suffering the ravages of Alzheimer's. There are even those who would "pull the plug" on him, with more sorrow than guilt, if it were legal. And when he does reach that stage, we often take no extraordinary measures to keep him alive, often at his earlier, explicit direction. Is it because there's no intelligence left in that body? Terri Schiavo was allowed to starve to death, and those who supported that course of action gave the rationale that her brain was so damaged that there was no intelligence left behind her eyes.
I think that's how most of us draw the line between abortion as permissible killing vs. abortion as wrongful killing. There's no doubt that a 34-week fetus is an intelligent being, learning faster than he or she will learn ever again. And there's also no doubt that a two-week old embryo has no intelligence yet.
Sorry this is so long. But if that isn't the explanation why most of us are opposed to 34-week abortions but not 2-week abortions, then I'd like to hear a better one.
