I was lucky enough to occasionally break out of that racist situation that prevails in the Hollywood film production community. But it was racist then and it will always be that way. It will never be otherwise.
The very first time I was on a car in Atlanta, I saw the conductor - all conductors are white - ask a Negro woman to get up and take a seat farther back in order to make a place for a white man. I have also seen white men requested to leave the Negro section of the car.
