But he doesn’t believe that significant gun control measures will ever meet approval in rural America, including a ban on AR-15-style semiautomatic rifles. He confided that many conservative police officers do not want more gun control and that other officers have told him that should they ever have to start taking guns away from people, they will quit their jobs. Like most rural conservatives, he truly believes that taking guns away from law-abiding citizens will never solve America’s gun problems, including mass shootings. He says gun control has never stopped criminals from getting guns, and never will.

To understand why many conservatives in rural America believe this, you must start with first principles, because the argument ultimately isn’t about guns; it runs even deeper than the Second Amendment. At a 2015 campaign event during the Iowa caucuses, J. C. Watts, the former congressman from Oklahoma, spoke about perspectives on original sin. It helps illuminate the differences in worldview between many conservatives and liberals. Mr. Watts said Democrats think people were born basically good, so when good people did bad things, something in society (in this case, guns) needed to be controlled. Republicans think the fault lies with the person — the perpetrator of the evil. Bad choices result in bad things being done, in part because the perpetrator lacks the moral guidance the Christian faith provides.

The reaction to mass shootings highlights this difference. Liberals blame the guns and want to debate gun control. For conservatives, the blame lies with the shooter, not the gun.

To my conservative friends, it’s a matter of liberty and personal responsibility. Even after a horrific event like the school shooting in Florida, where 17 people were killed, more gun control would be compromising those first principles. For them, compromising those principles would be even more horrific and detrimental to society than any shooting. What my conservative friends see is not gun control, but rather control, period.

Not everyone here is an N.R.A. nut, but they think the N.R.A. may be the last line of defense for the Second Amendment. The apocalyptic videos about gun control from the N.R.A. spokeswoman Dana Loesch are over the top, as my conservative friends here know, but they think they are fun for the basic reason that liberals grow faint after viewing them.
