Cosby was great for many reasons. But one reason is that, unlike almost every other show with African American characters, it didn't re-enforce the usual stereotypes to get cheap laughs.
It actually portrayed African American families in a positive light. Which was a life affirming experience for anyone who watched it. The show found humor in the human condition. Not cheap stereotypes.
Bill Cosby always got it with the example he has set.......for all of us.
Lifetime member of the "specific element" and proud of it.
