I admit, this went a slightly less rancorous path than I expected, so that's a bit of a win.
I find myself at a loss for direction, looking at all this. One side poses access solutions. The other people solutions (mental health, identifying). The former is much more actionable, but with less hope of an impact. The latter would be helpful, in theory, but in terms of scale and general functionality, deeply unrealistic.
In my younger years, I'd probably be all gung ho about gun control. But I got older, lived in a few armed homes. At least once felt that pacifying sense of thinking an armed roommate would deliver a measure of protection. And in truth, as we've said, the availability is there. Without counting law enforcement or the military, our guns outnumber people and are getting more concentrated. To put such a dent in the supply that it could tangibly matter, that would take generations with concerted effort.
And there won't be a concerted effort. The fact is, firearms make a lot of people feel very good. It's an interesting cultural quirk. Mdot said a gun was like a hammer or hatchet, a tool. But people don't get the way about hammers that they do about guns, at least not at scale (truth be told, the bad feelings about them are likewise over the top). In the end, they're most often a tool to kill, or to give off the possibility of killing, which is the mechanism by which they "protect." Ideally we'd have a clear-eyed functional respect, but in too many cases, firearms inspire a sort of fetishism.
That might be more worrisome than anything else. I'm not sure if we've got a deeper well of anger than past generations. It feels like it, but we also have access to more of the world. Our history certianly features a lot of anger, and there's plenty of it in the world day-to-day, but we seem to be enjoying it in different ways. Shakespeare wrote "these violent delights have violent ends," and if feels like we're embodying that in a lot of ways.
