doomsday has its day in the sun...,

NYTimes | Television has long been full of “Americans” (“American Restoration,” “American Chopper,” “American Hoggers”) and “Extremes” (“Extreme Marksmen,” “Extreme Makeover,” “Extreme Couponing”) and “Tops” (“Top Gear,” “Top Chef,” “Top Shot”). In recent weeks, though, an interloper has staked a claim: “Doomsday.”

Last month the National Geographic Channel introduced “Doomsday Preppers,” a Tuesday-night reality series about people who are stockpiling, arming and otherwise preparing for some kind of apocalypse. Last week it was the Discovery Channel’s turn. Its new “Doomsday Bunkers,” on Wednesday nights, is about Deep Earth Bunker, a company that builds underground getaways for the types of people seen in “Doomsday Preppers.”

Watch either show for a short while and, unless you’re a prepper yourself, you might be moderately amused at the absurd excess on display and at what an easy target the prepper worldview is for ridicule. Watch a bit longer, though, and amusement may give way to annoyance at how offensively anti-life these shows are, full of contempt for humankind.

“Doomsday Preppers” introduces an array of end-of-civilization types who at first seem surprisingly varied. These preppers live all over the country, in rural areas, suburbs and cities. Each has a different reason for turning a perfectly adequate home into a canned-food warehouse or building an escape hideaway (or bug-out location, to use the prepper term) in the mountains. One expects the North and South Poles to swap places, one a global economic collapse, one “an electromagnetic pulse that will disable the transportation system of the United States.”

But the people on this show and the customers of Deep Earth Bunker are more alike than diverse. Who knows how representative these shows are of the prepper universe, but the people they feature are disproportionately white. They can’t speak for long without employing that cliché involving excrement and a fan. And whatever their religious beliefs might be, something “Preppers” doesn’t generally explore, most of them put their real faith in firearms.

“Preppers” and “Bunkers” are both full of footage of people firing or lovingly cradling their weaponry, which in many cases is frighteningly extensive. (You really don’t want the guy in last week’s “Preppers” living next door; in addition to a house full of ammunition, he has stockpiled 50 gallons of gasoline, an unsettling combination.) One notable exception was Kathy Harrison, a New England woman profiled on a recent “Preppers.”

“It’s easy to feel a little left out of the prepper community if you live in New England and if you’re not fairly right wing and conservative politically,” she said in the segment. “But I just don’t spend my time worrying about stockpiling guns and ammunition, because our security comes not from stockpiling weapons but from having a community that respects each other, supports each other, and we have each others’ backs.”

A noble sentiment. But the unmistakable impression left by these programs is that what these folks want most of all is not to protect their families — the standard explanation for why they’re doing what they’re doing — or even the dubious pleasure of being able to say to the rest of us, “See, I told you the world was going to end.” What they want is a license to open fire.
