Let Intelligent Design proponents dally around with talk of “open debate” and critical assessment of multiple theories about the origins and mechanics of the world. Members of a focus group in Fort Worth, Texas, previewing an Imax documentary on Volcanoes get straight to the creationist point: any mention of evolution, however brief, is blasphemous and people shouldn’t have to put up the existence of non-biblical accounts of life, whether in schools or in strictly voluntary venues like commercial theaters. And like good entrepreneurs, several Imax theaters have listened, refusing to screen Volcanoes as potentially offensive to Christian audiences for a reference to the possibility that life began in undersea vents that they consider too likely to cause protests.
