I just saw this from September 2012 and thought ti was quite good. Jeremiah Goulka explains Why I left the GOP "This is the story of how in New Orleans after Hurricane Katrina and later in Iraq, I discovered that what I believed to be the full spectrum of reality was just a small slice of it and how that discovery knocked down my Republican worldview."
My old Republican worldview was flawed because it was based upon a small and particularly rosy sliver of reality. To preserve that worldview, I had to believe that people had morally earned their “just” desserts, and I had to ignore those whining liberals who tried to point out that the world didn’t actually work that way. I think this shows why Republicans put so much effort into “creat[ing] our own reality,” into fostering distrust of liberals, experts, scientists, and academics, and why they won’t let a campaign “be dictated by fact-checkers” (as a Romney pollster put it). It explains why study after study shows — examples here, here, and here – that avid consumers of Republican-oriented media are more poorly informed than people who use other news sources or don’t bother to follow the news at all.
Waking up to a fuller spectrum of reality has proved long and painful. I had to question all my assumptions, unlearn so much of what I had learned. I came to understand why we Republicans thought people on the Left always seemed to be screeching angrily (because we refused to open our eyes to the damage we caused or blamed the victims) and why they never seemed to have any solutions to offer (because those weren’t mentioned in the media we read or watched).
This does line up with John Haggerty's article a month ago, My personal Fox News nightmare: Inside a month of self-induced torture. "But now I was aware of Fox’s role as a purveyor, not only of right-wing information but of right-wing ignorance, and I began to examine my mind for things that I hadn’t gotten any information about in the past month. The most notable items that were missing, I realized, were people from other countries and poverty. Aside from the times when picturesque destruction video was available, there was essentially no coverage of foreign affairs. On the poverty side, programs like food stamps and welfare were generally referred to as handouts, and the only time poor people were mentioned was when they were a source of malfeasance...The effect of this is interesting. Even in my short time watching Fox I found poverty fading from my mind as a problem."
