People in the "heartland" area of America who are known for their cultural isolation and close-mindedness. Though they are a hard-working and sharp-minded folk, they have the tendency to look down upon you and derive pleasure from making you feel inadequate and stupid when you have essentially done nothing wrong, but rather merely spoken or acted in a way that is outside their limited, and to an extent ignorant, cultural understanding of the world. Confident and arrogant in their efficient way of life, they shudder when confronted with considerable or subversive cultural elements from outside their known world, and often reject them for the threat they pose to their identity and sense of empowerment.
Have you ever been to Chicago and spoken to Midwesterners? A lot of them are more shockingly ignorant than they may ever realize.
