One thing that you are not going to get about this situation if you aren't from North Carolina is that Duke attracts Yankees. Folks from north of the Mason-Dixon often don't recognize that there is strong regional feeling at work here. I worked all over the eastern United States. Folks from the North believe that North Carolina folks are ignorant and bigoted. Folks from the South believe kids from New York and New Jersey are arrogant and pushy. For both groups these feelings seem obvious and they assume that everybody shares their view-- a sort of "everybody knows...." sort of thing. These Lax guys are paying a price for generations of Yankees acting in ways that are appropriate at home and out of place in Durham.
To a North Carolina view, these kids are way out of line hiring a black stripper for a keg party. It's asking for trouble in their view. You can't expect the black community to be happy with a bunch of out-of-state white kids debauching their daughters, for money or not. They know this woman's reputation is spotted. Nevertheless, there are bound to be bad racial feelings and North Carolinians just don't go for that.
In North Carolina there are very few bars or clubs with nude dancers (virtually none).
Drink and violence, including racial violence, are linked together as well. North Carolina black professionals hardly ever drink in mixed race settings. It's part of the accomodation made to help an integrated society work.
There is trouble written all over this case from this point of view.
The bottom line is that the feelings that you see in letters to the editor and from the taunts of extremists involves more than a classic black/white opposition. It's region, class, manners and values, on top of race.
