Interesting, in relation to your point, a book came out several years ago called "Postville," that describes some internal strife in the town of Postville between orthodox jews and local natives. The writer was from EIU, but transplanted in from San Fran I think. My sister, a doctor at the EIU hospitals at time, but also from our tiny town north of Cedar Rapids, went to his talk about the book in IC. The dude did nothing but rip on Iowa and Iowans for their narrow minded views. So the dude bashes and stereotypes Iowans because of the conflicts going on in the tiny town of Postville. I was proud of my sister for calling him out for being hypocritical.
In another slightly different bashing of Iowa, this journalist from UC-Berkeley wrote a book on various farming methods in the world, focusing esp. on industrial and organic farming. Teri Gross on NPR interviewed him, and while talking about his section on industrial farming, he used an area in central Iowa as an example. When asked of the impacts of this practice of farming, he flatly stated "There is no biodiversity in Iowa, there are no birds in Iowa." I about blew my stack. I wrote the guy an email immediately, he replied back and apologized... I realize that many coastal lefties take NPR as gospel (like righties take Foxnews as gospel). I proved my point when an older couple I knew in Boulder commented to my girlfriend that "did you know there are no birds in Iowa?" Amazing what perception and mis-information can do.
