Are Fort Worth and Pensacola also filled with "overly polite Mormons"? Are they also "cartoonish examples of polite conservative locales"? (Congratulations, by the way, on making polite Mormons and conservatives sound like bad things.)
Conversely, are San Francisco, Ann Arbor, and Cambridge "cartoonish examples of crazy extreme leftists", or are they (unfortunately) typical of places where such congregate?
