It helps if you understand where, when, and how today's bunch of man-made rules began. In the early part of the twentieth century, Hollywood found that movies provided a lucrative method of introducing immorality, glamor, and worldliness to the general population. At a time of strict government laws against indecency, Hollywood fought for sin, and wealthy producers made a fortune doing so. A small number of rebellious women began wearing pants in public. Playing cards provided opportunities to gamble, drink, and neglect families.
A small number of churches objected, but these objections were not well-organized....yet.
