A humble black man can tell jokes about being poor and unappreciated that a rich white guy cannot. So, when that guy does the usual Rock material about race, what was edgy and hilarious becomes offensive and dumb. Our response to the jokes depends too much on the point of view of the person telling them, so the Rock jokes aren't funny when it's, basically, Donald Trump telling them. Fortunately, Rock is a consistently funny man. There is joy in his comedy, and heart and brains.
