I have 2 solutions.
#1 Start a Black Oscars. An all-black governing board could nominate as many individuals as they felt gave an above average performance. The top 10 nominees would get the top award, the next 50 would get a participation award.
#2 Start a new category at the regular Oscars. Call it the Oscar Whiner award. Give it to the top 10 whiners who complain about ethnic diversity.
