Racism on the Dance Floor?

I am currently reading Satan in the Dance Hall, and was particularly struck by the racist aspect of some of the objections to social dancing. Ragtime and jazz originated with blacks, and there seems to have been a strong objection to dancing to this music simply because it was 'African,' and had driving beats, which were considered indecent by many moralists. There seems to have been a movement to set 'respectable Americans' apart from the rest of the world - both on the dance floor and off. Prohibition was another aspect of this movement, and became tied strongly to the anti-dancing movement, as many clubs during Prohibition had both dancing and alcohol. As Lewis Erenberg wrote in Impressions of Broadway Nightlife, "Prohibition thus represented an attempt by urban, rural, and small-town Protestants to establish the hegemony of their familial values over the expansive values associated with a more cosmopolitan urban life." This seems to apply to dancing as well, as one of the principal fears was that young girls would be 'corrupted.' There were many unsubstantiated claims that young girls were being lured into dance halls and eventually abducted and sold into 'white slavery' as prostitutes. The fear of sexual promiscuity among young people and racism seem to be tied closely in this case, going back many years to first impressions of natives of the Americas and Africa as sexually promiscuous - partly because of their 'wild' dancing. I may attempt to find Rev. Straton's book The Dance of Death, as I am curious about his reasoning for condemning social dancing.
