I actually have seen the reactions of "traditional" black blues artists to white college boy blues artists, and , in general, they like them, and often like them a lot. And I've seen this same positive reaction in other ethnic groups, as well. People are flattered when outsiders take an interest in their culture, even when they don't get it quite right.

The disapproval tends to come from other college white boys, who fuss more about minor details of style than the traditional artists themselves.
