This Gay American Life, In Code or in Your Face.

''Hide/Seek: Difference and Desire in American Portraiture,'' a diligent exhibition centering on 20th-century portraits and self-portraits of or by gay artists, is now at the Brooklyn Museum, and it is more or less intact. Which is to say that once again, nearly a year after it was first mounted at the Smithsonian's National Portrait Gallery in Washington, it includes ''A Fire in My Belly,'' a four-minute excerpt from a video made in 1986-87 by David Wojnarowicz, who died of AIDS in 1992, at 37. Early in its run at the Portrait Gallery, ''Hide/Seek'' was abruptly divested of the Wojnarowicz (pronounced voy-nah-ROH-vitch) video, whose spliced-together imagery reads as a sometimes furious pictorial lament about human suffering. A brief close-up showing ants crawling frantically over a small plastic crucifix offended Republicans in Congress, who made threatening noises about the Smithsonian's financing. G. Wayne Clough, the Smithsonian's director, evidently agreeing that art should never offend anyone, immediately had the video removed from the show. (He later indicated that he regretted acting so quickly, which was small comfort.) That video, along with the longer version from which it had been excerpted by the show's organizers, became widely available on the Internet, and was in all likelihood viewed by many, many more people than saw the actual show.
