16 We must fight immoral and false literature with literature that is wholesome and sincere. Radio broadcasts, motion pictures, and television shows which make error and vice attractive must be opposed by shows which defend truth and strive to preserve the integrity and safety of morals. Thus these new arts, which can work much evil, will be turned to the well-being and benefit of men, and at the same time will supply worthwhile recreation. Health will come from a source which has often produced only devastating sickness.
