White Tulsa existed. And I am willing to bet plenty of racist isht went down that was widespread throughout the nation. A race massacre doesnt pop out of no where. They didnt have to bus in whites, they just walked over.
Your belief of some type of black oasis in the middle of no where is a gross fallacy, and a clear indication you think AA are somehow less. In your mind they couldnt have thrived if there were whites around, or rampant racism. Instead the opposite is far more likely. They were able to thrive with whites, and racism present. They were able to overcome, build up and support their community in the face of the challenges put on them. No idea why sjws want to shy away from that. It's another of the amazing tales about what makes Americans so great. But no, racists like you who cant see past their nose would rather believe an unsupported illogical fairy tale than admit the truth.
