There was no objection on the part of the NAACP then, they did not discreetly or publicly strip her of the award following her performance then. They have not said they will take back the award now. I am glad that the NAACP acted swiftly when outed but why must they be outed before they decry the comments as inappropriate?
Depends on how many local chapters there are. The NAACP is a voluntary organization, I believe. Each chapter may be chartered under the national chapter, but may be staffed by local folks and local volunteers.
It's not easy for the National folks to know everything the local folks are doing. It's like holding the National CPAs accountable if someone at the local level remarked at an annual dinner about how they "worked the system, wink, nudge" to help a client.
Would that be fair? No, it would not.
That being said, the NAACP should have been more careful not to throw stones at the TEA Party. Americans are no longer beholden to the MSM for their news, and people with cell phone cameras/recorders are everywhere.
Something unpleasant was bound to turn up eventually.
