By the title of your article, you’ve chosen to frame this in terms of “white sensibilities.” So in other words disobeying instructions, getting into arguments, acting nasty to opponents, “gamesmanship, cheating, manipulation, abuse, aggressive behaviour to umpires, to linesmen”—according to you, those are all black sensibilities. If I said such a thing, you’d (rightly) call me racist.
Maybe it’s just my white sensibilities, but I’m glad Djokovic beat him. I only wish he’d demolished him 6-0, 6-0, 6-0. Their skin color (and mine) has nothing to do with it; behaving with dignity and sportsmanship is not (or shouldn’t be) a “white thing.” How about focusing on the behavior and leaving race out of it?
