On a serious note, can I ask why you would not generally support such a ban?
I don't think it will help much. Why limit the liberty of tens of thousands for the safety of 6? Do we want to use that kind of math on other things that kills a handful of people a year? It's part of the problem of the gun control crowd, they want to ban things that sound scary, things they often don't really understand. Like when California banned new purchases of a specific .50cal rifle. Never mind that over the counter they are $10,000 weapons. No .50cal rifle has ever been used to commit a crime in California, but they were banned anyway. Why? Because they couldn't figure out why a person would need one and it sounds (and looks) scary. Look at the first AWB or look at the AWB2, banning things like bayonet mounts. As if people were getting bayonetted constantly. Oh that collapsible stock looks kind of like something a commando would use, can't have that! A pistol grip on a shotgun? That's right out!
It's difficult to debate people full of emotion and fear as I'm sure you know if you ever debated a Fundie. It's that much harder when those things are covered with a thick layer of ignorance and a strong feeling of superiority as I'm sure you know if you ever debated a Fundie.
