I'm for this. I'm also for raising taxes on ammunition. I'm also for limiting clip capacities. I'm also for an assault weapons ban.
I've heard all the arguments about how it would be ineffective, and how assault-style weapons only make up X amount of yearly gun deaths, and what is an assault-style weapon anyway, and slippery slope yadda yadda. But those arguments miss the point. It's not about an immediate decrease in numbers, it's about a slow cultural shift away from the glorification of guns. Up to now, assault-style weapons have been effectively marketed as, like, totally cool, and effective, and what, some sort of time-honored tradition? In turn, they contribute to this very American notion that guns in general aren't something to be feared, or even a necessary evil, but a tool worth celebrating.
Banning such weapons won't immediately turn back the tide of gun violence. But it would be a step toward re-framing the way we talk about guns. Policy shapes culture shapes policy shapes culture. Right now, our society still has what I and many outsiders would consider a sick obsession with weapons of war. We need to attack it from all avenues, not just the statistically significant or politically expedient ones.
One more note on assault-style weapons in particular. I believe it's not even a second amendment matter, it's a matter of the first amendment. Down to the broad taxonomy- "assault-style"- these guns have been advertised as A-1 killing machines. The marketing is inbuilt into their design- grip type, ergonomics, modifiables, color, shape- everything to remind us that they look and for the most part are built to act like the most efficient military models. And whether the pro-gun crowd likes it or not, they've become the de facto weapon of choice for mass shooters. They've taken on their own dark kind of brand recognition.
Speech is free until it's not. You can't yell "fire" inside a crowded theater. You can't direct marketing of cigarettes to minors, or even put an ad for such on TV. At what point does Bushmaster's effective marketing of their product become a public health hazard? At what point should manufacturers be regulated in how they build their product in order to sell it as a certain function to a certain crowd? I'd say we've long since passed that point.
