Here's Paul Waldman and Greg Sargent talking about AR-15s in the Washington Post (and I'll gift link again, so you should be able to read it all):
Indeed, among some Republicans, the rationale for doing little to restrict access to AR-15-style weapons seems untethered from any real-world considerations. Sen. Lindsey O. Graham (R-S.C.) recently opined that people need AR-15s to prepare for a future doomsday in which law and order breaks down entirely and police protection essentially vanishes.
Meanwhile, as The Post’s Colby Itkowitz reports, AR-15 variants have appeared in numerous GOP ads of late, and they are often brandished as little more than cultural signifiers. Assault-style weapons have taken on a kind of “own the libs” cultural life of their own: Rep. Marjorie Taylor Greene’s (R-Ga.) website recently enthused that such weaponry “TRIGGERS the Fake News Media and Democrats all across the country.”
Federal law seems decades behind this cultural shift. “The concept of what a long gun is in American culture has changed a lot in recent decades,” Mark Follman, the author of “Trigger Points,” a new book on mass shootings, told us.
Follman noted that the long gun was once understood as being primarily about hunting. But now, he said, rifles are increasingly marketed as a weapon of aggression and an “object of masculinity,” with a deliberate eye toward encouraging the “militarization” of gun culture.
In this sense, federal law is trapped in something of an anachronism. “The law may need to catch up with the way these weapons are perceived by 18-year-olds,” Follman said, citing massacres in Texas and Upstate New York.
There’s still another layer of perversity here. As Follman notes, mass shootings were historically carried out by semiautomatic handguns. “But that’s begun to shift in recent years,” he said. “More and more of these attacks are being carried out with AR-15s.”....
Ryan Busse, a former gun company executive who has emerged as a fierce critic of the industry, notes another absurdity: The age was set at 21 for handguns, Busse says, in part precisely because they were deemed more likely to be used by criminals against human victims than rifles would be.
“Now we have the AR-15,” Busse told us, which is the “most lethal, offensive thing out there.” Yet it isn’t treated as on a par with handguns, Busse notes, adding: “This demonstrates how behind-the-times our gun laws really are.”
The article is too softly worded, really: I would prefer if it more directly said that Right wing political paranoia and culture warring, encouraged by money grubbing Right wing pundits and the gun industry itself, is what stops reasonable gun control measures in the USA.
