"My old Republican worldview was flawed because it was based upon a small and particularly rosy sliver of reality."

It's all about the difference between illusion and delusion.

An illusion is a fanciful vision or a false impression or idea, a mental state in which one attributes reality to something unreal. Delusion is a mistaken impression or wrong idea, but the word also implies action - the action of fooling with a wrong impression or idea or the condition of being fooled or deceived.

Or, in the case of embracing the worldview of the GOP, both.

I dove into the research literature to try to figure out what was going on.  It turned out that everything I was “discovering” had been hiding in plain sight and had been named: aversive racism, institutional racism, disparate impact and disparate treatment, structural poverty, neighborhood redlining, the “trial tax,” the “poverty tax,” and on and on.  Having grown up obsessed with race (welfare and affirmative action were our bêtes noirs), I wondered why I had never heard of any of these concepts.

Was it to protect our Republican version of “individual responsibility”?  That notion is fundamental to the liberal Republican worldview. “Bootstrapping” and “equality of opportunity, not outcomes” make perfect sense if you assume, as I did, that people who hadn’t risen into my world simply hadn’t worked hard enough, or wanted it badly enough, or had simply failed.  But I had assumed that bootstrapping required about as much as it took to get yourself promoted from junior varsity to varsity.  It turns out that it’s more like pulling yourself up from tee-ball to the World Series.  Sure, some people do it, but they’re the exceptions, the outliers, the Olympians.

I'll skip directly to the conclusion, but the essay should be read in its entirety.

Why I left the GOP, by Jeremiah Goulka (tomdispatch.com, relayed by Salon)

I grew up in a rich, Republican household, but after Katrina and Iraq, I realized my priorities were out of order

 ... 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).

My transition has significantly strained my relationships with family, friends, and former colleagues.  It is deeply upsetting to walk on thin ice where there used to be solid, common ground.  I wish they, too, would come to see a fuller spectrum of reality, but I know from experience how hard that can be when your worldview won’t let you.

No one wants to feel like a dupe.  It is embarrassing to come out in public and admit that I was so miseducated when so much reality is out there in plain sight in neighborhoods I avoided, in journals I hadn’t heard of, in books by authors I had refused to read.
