Just an example:
https://en.wikipedia.org/wiki/Grant_County,_Wisconsin
Per capita income is: $20,758
Average household income is: $43,889
Reasonably large population: 51,208
98.23% white.
Probably don't really care if you culturally appropriate when dressing up as a geisha for halloween when the average person makes less than minimum wage.
And I also expect they don't like being told how easy it is being white.
