A Fire in My Belly by the late David Wojnarowicz, contains a brief segment depicting ants crawling on a crucifix. The piece, included in Hide/Seek: Difference and Desire in American Portraiture at the staid National Portrait Gallery in Washington, D.C., was denounced by the usual politicians, and removed from view after a moderate fuss. It could be worse: In Iraq, BBC reporter John Simpson met a man who had been dipped in a bath of acid for writing a telephone number on a bank note bearing Saddam Hussein’s face.
