It is more of a disrespect to future black president(s). A black president needs to be a normal thing from now on. Why would she feel it is disrespectful if the show has a black president that isn't Obama? But it is OK that it is a white president?
because she says people will compare the black presidents actions to Obama, giving a negative image to the idea/image of a black president. its a double negative, she can't win with y'all either way. if there was a black president y'all would be criticizing the show as being disrespectful to the president
