Well, Czarcasm, at least you didn’t quote the Kellerman study. 
Wait, don’t flame me yet, I have a lot to say here. Seriously, though, I just got up and haven’t had time to see if these cites have been discussed here before - it’s possible they may have, considering that they are from pretty reputable journals. Without even seeing them, however, if Kellerman is the author/co-author of one, or he is cited as the source of the other study, well…then I can reject it out of hand.
If not, then I would like to see how they are defined. I actually had all of those journal issues here, and read a couple of them, but the Ex took them with her. I will not be the one to claim that the studies are questionable in any way - unless Kellerman or his generously massaged data is used in them.
And admitting that there is a higher risk does not bother me in the least, really. Saying that a “having a home with a gun in it is 5 times as likely to end up in the murder of a family member” doesn’t take into account my personal situation. I certainly don’t lump my actions in with the rest of society, and thus a statistic like that is meaningless to me. Just as meaningless to me is one that would say “having a home with a gun in it is 5 times less likley to end up in the murder of a family member”. Either way, the majority of the time it is my own actions, responsibilites, etc. that lead to my consequences.
All of the freedoms we exercise have risk, and the thing that doesn’t get discussed much here, which I brought up ages and ages ago, is: “How many children must die in accidents from firearms misuse by others to justify Anthracite not being raped again?” Now, on the surface this is a specious argument. But let’s think about it, because maybe it is the core of what the whole argument really is about.
So…how many innocent children is my protection worth? It’s a hard question to ask, and even harder to answer. We know there will always be accidents, so I know as long as I can have a gun like other people, the risk must be non-zero. As long as there are firearms, there will be accidents. Experienced police officers, military personnel, Olympic-class target shooters make mistakes. The rate is miniscule, but not zero.
It’s also akin to saying "How many children must be exposed to hard-core pornography so that Mr. Weird Al can buy his lesbian skin magazine (sorry Weird Al
)? The difference is that “Being exposed to pornography” is not really as bad as “being shot”. The magnitude is different, but the principle is the same. Freedoms with costs - sometimes terrible costs. How does one balance keeping the Freedom with reducing the costs? 
How much is a child worth? A hard, or possibly callous question, but this is the SDMB, where we are used to asking the hard questions. In an impromptu debate at work, over lunch, this question was put to my co-workers. The answers ranged from “I’m not going to answer that” to “Infinite”. Really? I said “so your child is worth more than the lives of everyone else in the World, including mine?” and the answer was “Yes.” Hmmm… I’m guessing that few people will ever be able to agree on the cost of the life of an innocent, especially if it is their own child.
How much is my right to protect my body and life, with a means that actually has a chance of success, worth? How much is it worth if a woman is not raped? The woman might say infinite - but how does it compare to a child-life of value? Is it 1/1000 child? 1/100? And please, the wanna-be Bruce Lee’s can stay out of this. No 5’ tall, 120 pound woman is going to have a serious chance of defending herself against the 6’4" 280-pound linebacker who decides that he didn’t get enough sex today - unless she has an equalizer. I doubt if I could swing a baseball bat hard enough to not have it taken away from me. I doubt that a stun gun will actually deter someone, plus it puts me too close to them. I doubt that if I went to a Shao-Lin monastery for 20 years that I would be able to do much against a determined, much larger and stronger man out for his nightly-rapin’. But I’m skilled with using my handguns, I’m practiced, and most of all, in the darkest of the night, all alone and pondering, I have come to the answer that I have the will to kill someone who is attacking me. If I had a person at gunpoint who seriously threatened me, and I demanded they stay put, and they pulled that stupid-ass “Hollywood trick” of walking slowly forward, hand out, talking in those patronizing male tones of “Now, give me the gun…” I would shoot them, and they would get a .44 caliber hole in them, and they would die. And as I posted earlier, I know what the consequences will be. And I have accepted them.
And this is why this question can never be answered, and why these debates will continue. It is impossible to define the value of my right. And it is impossible to define the cost of my right.
