Did you ever live in New Orleans? Because the vast majority of blacks in New Orleans are working-class, living in intact families, typically extended families living together in the same community.
Most of the unique aspects of New Orleans culture is from the black Creoles -- the music, the food, the architecture. Black Creoles write and play New Orleans jazz. Black Creoles cook and serve New Orleans cuisine. (Emeril is from Massachusetts!) Black Creoles built the beautiful houses, and crafted the wrought iron, and tend the gardens, and maintain and drive the streetcars.
Without black Creoles, New Orleans would be another Shreveport.
