"The Mann thing has had a clear affect on you. That comment, in which you hinted about the identify of an anonymous commenter, is something a couple of years ago, you came on someone else about. It was a wrong turn."
Those are the words Charlie wrote to me and he is right.
The sadness and frustration I feel over the Mann situation should not have colored my judgment. It's not an excuse but an explanation.
I apologize for any discomfort I caused. I regret my statement and it won't happen again.
(I will say that I did reach out to a number of groups that support closing the achievement gap for African-American students to ask about their support of the Mann group and did not ask just one group.)
