Personally I agree with Christopher Knight of the LA Times.
Objectively speaking, an artist bent on making an anti-Christian diatribe would not spend just 15 seconds of a 13-minute video making it. Those images instead serve another function: To rebuke the same self-righteous moralism of those who are attacking the Smithsonian now.
Ants and bugs are an age-old artistic symbol that laments the frailty of human beings and earthly existence. As Ecclesiastes puts it: Vanitas vanitatum omnia vanitas -- “Vanity of vanities; all is vanity.” Ant-covered flora, bodies and animals turn up in everything from still life paintings in the largely Protestant 17th-century Netherlands to the silent Surrealist film, “An Andalusian Dog” (1929) by the Spanish director Luis Bunuel and artist Salvador Dali, a conservative Catholic.
In the Wojnarowicz video, the vanitas theme plays out on a crucifix not as a religious slur, but as a lament for earthly failures among those who should know better at a time of epic tragedy. Small wonder that some who failed then take offense at being reminded of it now.
I am reminded as well of Jesus in Scorcese's Last Temptation of Christ.
