First let me clarify that I support the rights of besotted owls everywhere. Some of my best friends are besotted and have been know to say "who?" when accused of such. They are not deserving of persecution. Everyone has the right to descend into a drunken stupor. It has a long and proud history and is one of the things that made America great. Long live the old growth forests!
To the main trust of your post, I think your analogy is flawed. Since I, and our laws, don't consider a fetus as a human being, there is no human suffering to balance against this protection of a women's rights. This is the real crux of the issue. As long as we are in disagreement as to what constitutes a human being, then we can't really understand each other's positions. This is why I feel we should worry about those already alive & create the good birth control. The birth control avenue solves the abortion conundrum.
But if your analogy was true, I'd probably say that the protection of societal rights is more important than a given person's life. I think this is the reasoning behind capital punishment (which I don't support and waging war for freedom (which I do support).
