Conservative groups have turned the documentary “March of the Penguins” and “its stirring depiction of the mating ordeals of emperor penguins into an unexpected battle anthem in the culture wars.” This is “the motion picture this summer that most passionately affirms traditional norms like monogamy, sacrifice and child rearing. This is the first movie they’ve enjoyed since ‘The Passion of the Christ.’ This is ‘The ‘Passion of the Penguins.’ In part, the movie’s appeal to conservatives may lie in its soft-pedaling of topics like evolution and global warming.”
