One moron does not equal the population of the whole state.
I know my neighbors are not that grade of moron, but they would not hear me or anyone else in my house cough. Because our windows and doors are shut.
Humans being what they are, I'm sure that Kansas and North Dakota and etc. have their per capita share of busybodies. They just lack their per capita share of bashers on conservative discussion sites.
As a North Dakotan, in town, sure, there are those few who know how many cans were in their neighbor's grocery bags by the bulges in the bag. Everybody needs a hobby, i guess.
Once you get out of town, though, that requires either some fantastic optics, a drone or both.
We do have a tendency to look after each other, but privacy is one of the reasons houses have walls.
