So if that same kid beat his sister with a pool cue, you'd be arguing for pool cue control? Maybe you could sue CueTech or Predator or Tempest for marketing a lethal weapon? Not making it child-proof? Not containing sufficient warning?
Gun ownership is a responsibility. Just like driving or owning large growly dogs. People who FAIL in their responsibilities should be prosecuted and possibly lose some privileges, but don't focus on guns. Guns kill a lot less people in this country than driving or smoking. And both of those things, like guns, are still legal. As is abortion, and that probably should be legal and available because otherwise, illegal abortions will kill young women. Third trimester procedures are probably something else altogether, and should probably be a different discussion.
As for the abortion "argument", it is interesting to me that pro-choice people maintain a certain respectful vagueness around the issue of 'what to call it' and that's what Jough is pointing to. Sure, it would be basically impossible to build any polticial or social will around an argument that says "I want the right to choose to stop a biological process that will result in a human being" which is what it is regardless of when you decide to say there is a 'life' and to take away the charged word 'kill' which is an unfair term to use if you can't decide if there is 'life' in the first place. A big problem in this debate is an inability to agree on terms. Without that, it's political rhetoric on both sides and probably, as Cort points out with the theological argument, always will be.
Many abortions end pregnancies that are a result of irresponsible behavior. There is a need for both men and women and certainly boys and girls to comprehend the responsibility and potential consequences of unprotected sex (in terms of disease and conception) because the consequences become social as well as personal and, in the final analysis, the consequences affect all of us. Abortion is one consequence but not the first or most important one on my list - AIDS and other STDs, infertility, the number of unwanted or neglected children, drug-addicted children, children growing up in poverty, children who are supported by the government are bigger problems than abortion and clearly these problems are not being solved by abortion.
If we could somehow morally justify encouraging more responsible reproduction (separate from the issue of having sex), we could be better off. This could be an argument for long-term, stable relationships which some marriage proponents would use. I'm not going there, because it's a doomed argument, but I imagine the number of married women seeking abortion is pretty small compared to the unmarried, although I myself personally know at least one exception to this.
People interested in both a healthy society and money being spent on progressive programming like school improvements or health promotion should argue less about abortion (states don't pay for abortion, generally) and think about how to have less conceptions occur. It's a lot more financially sound in the long run, has less psychological cost than abortion and gives us something more positive to discuss instead of a polarizing issue to be 'for' or 'against'.
