People from the midwest. Incorrectly stereotyped as:
Conservative (in actuality, the midwest is very balanced between liberal and conservative)
Stupid (Some of the best public education in the nation is in the midwest)
Correctly stereotyped as:
These people are some of the nicest you'll find anywhere. They aren't as interested in materialism and greed as others in America. Very good work ethic.
East Coaster: You midwesterners are stupid hicks, fuck-bag.
Midwesterner: I'm sorry you think that. Would you like to come in for some dinner?
East Coaster: I feel really guilty for being so mean and making such horrible generalizations about such a nice person.
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.
