And yet ... I think the biggest problem with our neighbor's example is that it is overly complex.
We could dig up the sad tale of any number of NFL stars. It would be one thing to say the owners admit it, but that would mean they think there is something wrong. And we, as a society, spend the whole time teaching young people that conduct off the field is just as important as on, but once money enters the game, at the college and university levels, that rhetoric is just for show. Testosterone-charged warriors suffering routine head injury are not going to work and play well with others; at some point we ought not be surprised at off-field violence.
Removing laws against violence off the field won't help anything, of course, but if we stand in the middle of the violence and look out at the marketplace, what we see is that the American people want it. That is to say, if a murder here, a few wife-beatings there, and serial rapes there, there, there, and there—oh, and there, too ... and there ...—are the price society has to pay in order to watch men kill themselves and each other slowly on a football field, the attitude generally runs, (1) as long as it's not me and mine, and, (2) as long as we don't have to say it out loud, well, yeah, sure, Americans are okay with the toll.
As long as it is not that person paying the price, or the people that person cares about, and as long as we don't ask that person to say it out loud, yes, the mass shootings have been an acceptable price for our cowboyish hero fantasies and other aesthetic satisfaction.
Consider American football: Without the spectacular violence on the field, football is not a massive spectator extravaganza. And in accepting the price, the off-field violence, Americans are also willing to engage in the same victim-blaming they always do when they find accusations inconvenient to aesthetics.
(Okay, this part sounds a little digressive and, for its own part, complicated, which is why it is reserved to a parenthetic note: Consider singing in the shower. Now ask, is the most popular music "the best", and by what criteria? The point being that plenty about music is not appreciated within the pop market context. The Fibonacci aspect of Tool's "Lateralus" is cool, and all, but fewer people hum that in the shower than the latest candy-pop flavor of the week. Similarly, if we note contemporary complaints about violence in movies and video games, we must also consider what sells and why. People somehow feel they can relate to some aspect of the art they prefer; it is easy enough to understand the pop accessibility of The Lost Boys, or an A-list cast mixing the sexy vampire lore of a bestselling novel like Interview With the Vampire, compared to Nadja; the innovative filmcraft is the least accessible, in this case. Nietzchka Keene directing Björk in The Juniper Tree results in a breathtaking film; there is a reason, though, more Americans prefer the dry cool wit of an action hero surviving a volley of ridiculous gunfire. In the end, this is about aesthetics, and as long as we don't have to say it explicitly, and the death toll stays far enough away from us, what happened in Parkland, or Sutherland Springs, or Las Vegas, is just part of the price of our satisfaction.)
One other aspect worth noting:
It's not entirely problematic, but this is an unusual equivocation of generally different applications of the word, "sport". As with the well-regulated militia, if the gun owners wish to form, say, rifle teams, and practice and compete, and all that, we have a similar context of sport. If, however, we look for the sporting analogy to the sportsman with his rifle, we're watching Eugene Morris Jerome pitch baseballs against a board in his Brighton Beach backyard, circa 1937, or heading out back to throw footballs through a tire swing. The bit about someone dying when we miss is not exactly a loose end; it tends to make or be a certain point of its own.
The National Rifle Association, furthermore, is not, as it presents itself, a sportsman's or sporting group; they are an industry lobby. When we hear their recommendations, remember: A world so chaotic that the best solution is, "Buy a gun!" is the world the firearms industry wants the rest of us to live in.
