Not directly related, but a fun comment on this whole issue in general.
I've heard it said that the people in the south are polite on the outside, and black-heartedly evil on the inside.
Conversely, everyone in New York is evil on the outside, but somewhat good on this inside.
All I know is some guy from Georgia said it, and he thinks its true.
Anyway:
Ah, stereotypes. They're such mean little devils, but I can't help but feel that to some extent they are propagated by the people who fill them. Not all people who are stereotyped are the stereotype, by all means no, but I at least know that for me, whenever some kids who dress gangsta walk in my taco bell door, all I have to look forward to is them paying two bucks for two of our burritos, and trying to get soda from asking for a water cup. Then they turn into teenagers and curse everything third word, usually the N~ one in all its many variations, and talk with a fake accent that, to me, makes them sound stupid. And every time I hear that accent, its what I come to expect.
So I stereotype, though I try otherwise. But if they just were a little more honest, or just as a group acted a little differently, it would be a different stereotype, and maybe not a negative one.
And there is always the one black military man who comes through, a sergeant, who I have heard go off on a group of teens for simply saying N~ once, to the effect of, "I and my family have not fought, sweat, and died for over sixty years just to have that word continue to exist."
Surprises always happen.
Fun fact: you essentially stereotype everyone you see. You have a set of expectations, or a preliminary judgment based on what you see. I'm not saying you're stereotyping per se, but most schools attempting to teach you something about getting a job and working through interviews inform you that the person you're being interviewed by has already made a decision in thirty seconds. I would say it safe to say that everyone does this, all the time.
