Audience Approval of What in Sherrod's Speech?

William Saletan does a careful analysis of the audience's reaction to Shirley Sherrod's speech.  My own reaction, which I've hesitated to state because I don't have a lot of experience listening to majority black audiences responding to black speakers and ministers, was that they were giving the audible feedback which seems to be the norm in such settings.  Saletan's analysis is much more careful than that, and convinces me that Breitbart's claims are wrong.
