The mixing of cultures is exactly what many people are afraid of. They think, rightly, that mixing results in changes to what they think of as “their” culture. People naturally perceive change to be something scary and to be resisted, not realizing that change is the rule rather than the exception, so they harass and bully to try and reassert the dominance of “their” culture over the frightening other.
On the subject of entertainers though, the history of hybridization is not so hopeful. At least since the late 1800s, white people have been adopting elements of black culture to their own benefit while the people who actually invented those elements get mostly left out. There is a direct line that can be drawn through most of American popular culture that expresses this dynamic: minstrel shows and ragtime, the blues and jazz, rock and roll and rap were all a part of this process. Somehow, all of these art forms have ended up financially benefiting white people far more than blacks. Prejudice has a great deal to do with that pattern regardless of how hybridized the entertainer might be.
