"Bishop's book tells the story of how we've geographically, politically, and even spiritually sorted ourselves into like-minded groups in which we silence dissent, grow more extreme in our thinking, and consume only facts that support our beliefs--making it even easier to ignore evidence that our positions are wrong. He writes, "As a result, we now live in a giant feedback loop, hearing our own thoughts about what's right and wrong bounced back to us by the television shows we watch, the newspapers and books we read, the blogs we visit online, the sermons we hear, and the neighborhoods we live in." This sorting leads us to make assumptions about the people around us, which in turn fuels disconnection. Most recently, a friend (who clearly doesn't know me very well) told me that I should read Joe Bageant's book Deer Hunting with Jesus. When I asked him why, he answered, with contempt in his voice, "So you can better understand the part of America that college professors have never seen and will never understand." I thought, You don't know a damn thing about me, my family, or where I come from."
