I always hated that show because he called white people all kinds of names and the audience laughed about it when if the shoe was on the other foot, well you know.
It was a sign of the times, Gina. And, it was a NEON SIGN for producer Norman Lear, a card-carrying liberal who felt that the black man was being held down.
So he put together shows like All in the Family (Carroll O'Conner shown to be a racist, bigot, and all-round dufus); Sanford and Son (black man and his son tryin' to make good in this worl'), and The Jeffersons, along with a few that I've forgotten about.
You might recall that one of the signatory developments of The Jeffersons was the portrayal of a white man (character name Tom Willis) and his black wife Helen. That may have been one of the first TV castings of an interracial couple between a white man and a black woman.
