It's a complete myth, one that people like Farrakan or the NAACP love to perpetuate. Go into any nice "gentlemen's" club in America, and you won't find many black dancers. Most black dancers dance in black clubs for black men. Why? Because the overwhelming majority of white men don't even want to watch a black woman do a lap dance. It's not racist. It's preference, just like the black guys who like to have black women dance for them.
I've been a white man a long time, and I've never once heard any white man talk about wanting to have sex with a black woman, or even alluding to, except when Halle Berry was mentioned.
Good point. I'm going out on a limb here...but I used to "go-go dance" when I was in college (not my finest hour, but I needed the money and did not use the best judgment). This was in the early 80's. There was a big difference between those of us who "danced", and those girls who "did parties". And I have to tell you, there was a big difference in the types of places we would work, and the types of girls who would work them. The go-go bars that I worked at were in white neighborhoods, and most of us were white. We wore bikini type tops, in fact pasties were illegal and you would get fired from the agency for wearing anything close to them. I had an agent, and he had to send most of the black dancers to black bars, because the bar owners just did not want the black dancers, because the white men preferred white dancers. But even among the girls who "did parties" there was a heirarchy. The lowest of the low were girls who worked at parties without their own bouncers. It was just insane for any girl who knew that environment to consider it.
