I remember a Circuit Assembly part about it, along the same time as being against Dungeons and Dragons.
I later learned that the WTBS was only against Dungeons and Dragons because of Gary Gygax (the game developer) who had been DF'd by the WTBS. The WTBS essentially carried on a war against Gary for years with Witnesses. I was always curious why Gary G. didn't just sue the bastards for trying to ruin him economically. In any event, Dungeons and Dragons became a HUGE success.
