Earlier this week, we reported that a Dartmouth College fraternity apologized profusely and took steps to repair the outrage, which occurred after they hosted a “Crips and Bloods” costume party.

Of course, no amount of hand-wringing is ever enough for some of the most aggressive and aggrieved “civil rights” groups:

The Dartmouth College chapter of the National Association for the Advancement of Colored People (NAACP) harshly criticized a “Bloods and Crips” themed-party, despite apologies from the sorority and fraternity that hosted the event earlier this summer.

The strongly worded letter, penned by the NAACP chapter on campus, and signed by the Afro-American Society and the Dartmouth Chapter of the and Women of Color Collective, accuses the mostly white students of hosting a “racist” event thinly veiled by the South Los Angeles gangland theme.

“Our peers mingled for hours while dressed as bloods or Crips while using racialized language,” accused the letter, circulated on campus. “It then turned into a ‘ghetto party’ with racialized language, speech and dress. Over 200 individuals attended this racist and classist event.”

The letter went on to urge students to report the event to the Dartmouth administration “as a bias incident” using an included hyperlink.

“We are asking everyone to flood the bias incident account with our call for justice, right now,” reads the email. “[O]rganizations across campus will be mobilizing for further steps. Reporting with the above link is our first step toward meaningful changes.”

That link leads to the college’s bias incident reporting page which promises to direct all complaints to the the Office of Pluralism and Leadership, and the office of Safety and Security.

According to a popular Dartmouth blog, the Dartblog, however, the NAACP’s letter came after apology letters from both the sorority and fraternity that hosted the event.

“The idea was never meant to be derogatory to any group, and was intended to introduce a costume theme to the party,” wrote the fraternity, Alpha Delta. We “now realize that it was insensitive and thoughtless to make light of a very serious issue.”
