After your previous mistakes, you really should try to back up claims like this. In fact, given your previous mistakes, you should perhaps question yourself whether it's even true.
I think he's referring to the stats about a gun in the home being much morel likely to be used against a loved one than it is to be used for defense. That is to say, the rate of accident, suicide, and intentional criminal use outstrip the use as a defensive tool. This is problematic for a few reasons, the most obvious of which is that reliable numbers on defensive uses are really hard to come by. I'm fairly confident that the main thrust of the point is accurate however.
What that stat
tells us however is far more open to interpretation than what it is routinely cited in support of. There are a number of factors that drive this stat besides the possibility that guns are bad tools for self defense. For many gun owners, like myself, a gun is a tool and toy and not owned for self defense. The chances of me needing a gun to defend myself are rather low, but my chances of being able to employ them in self defense is even lower. I don't carry them around, and my ability to go to the building where I do not live and where they are secured, unlock the rack they are locked to, unlock the trigger lock each one has, go to the different room where the ammo is stored, and unlock the safe in which that is kept, and load them to use in self defense is well, slow. If I had immediate need of them I would not be able to get them. But then
that's not why I have them. My chances of using them to shoot targets or hunt are much much greater based on the simple fact that that's why I have them in the first place. So the number of successful uses of self defense for many gun owners like myself is
completely irrelevant.
Now in my view there are people (unfortunately a LOT of people) who own firearms for the explicit reason of defending themselves who have very, very little chance of ever needing it for that purpose, don't do what they need to do and follow the practices they need to practice to achieve that end safely, and usually both. This again doesn't mean that guns are ineffective or intrinsically bad tools for self defense, but that a lot of people are using them wrong. If someone doesn't practice, doesn't follow safe storage practices, doesn't learn and practice proper target identification and situational awareness, and doesn't live or work somewhere dangerous, then of course the chances of accident or misuse are much higher than defensive gun use. It also doesn't mean that people who do follow/do/have those things can't use them effectively. That's like saying fire extinguishers can't stop some fires from spreading because people use them wrong and derive a false sense of security from just having one.
I think a lot of these people who haven't educated themselves on the limits, dangers, and practices of owning a firearm need to not own them. They should learn that personal security is ten parts situational awareness and prevention, two parts conflict resolution, and one part force. Hell, I'm probably overestimating how many parts force still. The best way to achieve this without unduly burdening others seems to be the main sticking point.
How this relates to kitchen knives? Well about that...There are many ways to help prevent and avoid violence with them to when confronted with it that aren't guns, although that works well too. It's only tangentially related to guns, but directly related to violence and self defense.
