White symbolic tradition

In the 60's and 70's there was a white symbolic tradition of exposing the racism that plagued us, by producing and writing shows on television such as Kojak,Rifleman,Magniificent 7,Rebel,Wanted Dead or Alive,Hill street Blues, which showed at least the white liberal was concentrating on the evils that was existing in white America's ideology!Of course the black producers such as Spike Lee contributed to a lot of the foresight on what racism was doing to our black communities!Now the white producers don't produce anything but trash and the black producers follow their lead,such as Scandal,and bullshit like Walkin Dead!Food for thought!
