There may be a phenomena occurring that has long term cultural significance. There is coming to the forefront black conservative leaders such as Senator Scott, Georgia US Senate candidate Hershel Walker, Virginia Lt. Governor elect Sears and others who are achieving office and power. It reflects a deep resentment among many blacks regarding the real harm that patronizing, socialist policies have done to their community. It is respectable, especially in the South for blacks to identify and advocate as Republicans on their own terms. Worth watching. The current core political dynamic may be changing since the phenomena also seems to be occurring within the Hispanic community.
The rant itself was instructive, but what precipitated it was even more important. The timing of it was not a random coincidence. Cosby was complaining about the failure of the civil rights movement precisely because that year marked the first time in history that Hispanics surpassed blacks as the largest minority group in the U.S.
At that moment the writing should have been on the wall for every black American. Nobody needed to pander to them anymore except for fading, pathetic white politicians. You had winning candidates like George W. Bush and Barack Obama speaking campaign slogans in Spanish, while nobody was speaking "ebonics" on the campaign trail except a broken-down old white loser, Hillary ("Ah ain't no ways tahrred!") Clinton.
