Putting aside matters of taste and sensitivity, Jimmy Kimmel felt free to do blackface skits 20-plus years ago (Comedy Central’s The Man Show, a song from a 1996 comedy Christmas album) because he thought they were reasonably funny and nobody would say boo. Which is what happened until recently. The same calculation and risk assessment was made by Robert Downey, Jr and Ben Stiller when they made Tropic Thunder. And then the culture changed and now everyone who attempted this kind of risque comedy has to apologize. Not a biggie and certainly not an indication of toxic essence. The goal posts have simply been moved. Burt Lancaster wore black-guy makeup in Scorpio, a 1973 Michael Winner spy film. Big deal.
