The gun issue is a classic example of how what I call the Dirt Gap divides up the U.S. into thinly populated Red Regions and densely populated Blue Regions. I wrote in The American Conservative back in 2004 in "Baby Gap:"
The endless gun-control brouhaha, which on the surface appears to be a bitter battle between liberal and conservative whites, also features a cryptic racial angle. What blue-region white liberals actually want is for the government to disarm the dangerous urban minorities that threaten their children’s safety. Red-region white conservatives, insulated by distance from the Crips and the Bloods, don’t care that white liberals’ kids are in peril. Besides, in sparsely populated Republican areas, where police response times are slow and the chances of drilling an innocent bystander are slim, guns make more sense for self-defense than in the cities and suburbs.
White liberals, angered by white conservatives’ lack of racial solidarity with them, yet bereft of any vocabulary for expressing such a verboten concept, pretend that they need gun control to protect them from gun-crazy rural rednecks, such as the ones Michael Moore demonized in “Bowling for Columbine,” thus further enraging red-region Republicans.
