Then too, until America starts to value brains and questioning above sports and marketing, academics will stand apart from the mainstream. That isolation can breed innovative words, but it also promotes self-defeating anger. Political correctness will not go away until suffering ennobles. I will not hold my breath. But whenever art looks puzzling, it may sound odd or offensive as well.
Artists work with difficult materials, ideas, and impulses.
Their influences and audiences have a specialized history, too, and art makes sense only when one makes the effort to understand all these. A gallery-goer who feels left out by street talk in SoHo would probably find it tough going in the Bronx, too. So artspeak stems from critical failures, social divisions, and indeed the very needs of art. Try an experiment. Take the books by neoconservatives decrying radicals and the decline of standards.
