First of all, there is no straw man. Straw man arguments erroneously restate arguments and then attack the restated argument. At best, you've got misunderstanding the nature of statistics or observational selection.
Second of all, I didn't make the argument. There was a graphic posted not too long ago, and by someone else, that had an AR15 and a hammer with numbers for each. Now, neither number more than likely represented the actual numbers of death by each instrument, but the intent of the graphic was that if you're going to ban a specific firearm, which has numbers of deaths so low, then why not another tool that has low fatalities. The numbers on the graphic had rifles, all rifles, being lower than blunt instruments.
We're not discussing "guns," we're discussing a specific firearm that is attempting to be banned, even though it accounts for a very small percentage of deaths by firearms overall. There is no reason to read anything more into it than that, but I see that you've managed to do that anyway, and made a nice little straw man of your own since no one is making the specific argument you stated.
Finally, the overall intent of the graphic was to show the illogic of banning a specific firearm that accounts for so little deaths when there are comparable numbers for other objects, especially given the reasoning of wanting to "save lives." You want to "save lives?" There are a host of things you can ban that have numbers that make firearm deaths look like nothing.
Now, I understand that the argument comparing guns to hammers has been made by politicians and the like, and I can certainly agree that it was erroneously made. But that's neither the argument being made here, nor does it have anything to do with the overall intent.
