MANY hours into the 82nd Academy Awards ceremony this Sunday, the Oscar for best actor will go to Morgan Freeman, Jeff Bridges, George Clooney, Colin Firth or Jeremy Renner. Suppose, however, that the Academy of Motion Picture Arts and Sciences presented separate honors for best white actor and best non-white actor, and that Mr. Freeman was prohibited from competing against the likes of Mr. Clooney and Mr. Bridges. Surely, the academy would be derided as intolerant and out of touch; public outcry would swiftly ensure that Oscar nominations never again fell along racial lines.
Why, then, is it considered acceptable to segregate nominations by sex, offering different Oscars for best actor and best actress?
Since the first Academy Awards ceremony in 1929, separate acting Oscars have been presented to men and women. Women at that time had only recently won the right to vote and were still several decades away from equal rights outside the voting booth, so perhaps it was reasonable to offer them their own acting awards. But in the 21st century women contend with men for titles ranging from the American president to the American Idol. Clearly, there is no reason to still segregate acting Oscars by sex....
