I've never seen a study, but my sense is that these are people who feel really aggrieved. These people think, "I've done everything right all my life, I'm a god-fearing Christian, I'm white, I'm male, I've worked hard, and I carry a gun. I do everything I'm supposed to do. And I'm getting shafted." And in fact they are getting shafted. For 30 years their wages have stagnated or declined, the social conditions have worsened, the children are going crazy, there are no schools, there's nothing, so somebody must be doing something to them, and they want to know who it is.
