If you go over the line in making fun of a group of people, then you merit the social opprobrium that comes with that excess. This kind of activity should not merit "official" intervention, to include the requisite tearful apologies and threats of legal action from the NAACP (what laws were broken, again?).
BALTIMORE - Johns Hopkins University has suspended the Sigma Chi fraternity because of a "Halloween in the Hood" party that drew protests by black students.
The invitation to the party, posted on the Web site Facebook, encouraged guests to wear "regional clothing from our locale" with jewelry including "bling bling ice ice, grills" and "hoochie hoops..."
Black Student Union members protested the party on Monday, saying the appearance of the image and the language on the invitation highlighted racial tensions at Hopkins and the strained relations between the university and the surrounding community...
University officials suspended all the fraternity's activities pending a full investigation. President William Brody said in a statement that he was "personally offended" and called the matter "deeply disturbing."
I'll bet that if they threw a Hillbilly Party, or a NASCAR party, or a WASP party--in other words, anything mocking red state voters--they'd be given the prize for most entertaining party.
And if others threw an ordinary party and came dressed the way the Sigma Chi brothers mocked, no one would think anything was peculiar.
I guess some people are more equal than others.
