Hold on. Logically speaking though, why would a women in MODERN times and the age of the internet, hire a pimp for defense? Pimping business is done, sorry fellas! Women don't need black or white pimps for security. And maybe only a certain few do, but it's highly unlikely given the law favours them. And for god sake we're in Canada, the Johns aren't that very threatening (rarely)...
So I am going to believe that it isn't racism, but mostly due to experiences... And I actually have asked the ones who say "no black men". They all tell me the same thing - "young black men are dangerous".
