When my husband was an elder and on a shepherding call, was instructed by the other elder to check the videos in the cabinets, even opening the door. My husband refused but it made him think about the Big Brother tactics being used.
He said the CO instructed the elders that they were not to be going to R-rated movies or renting/buying R-rated videotapes. The CO gave a talk about R-rated movies on cable channels and that were not edited enough to make them acceptable to a "real" Christian.
I personally think each individual is capable of making their own choice.
But note the manipulative comments in this WT:
*** w82 7/15 24 Benefiting From Your God-given Conscience ***
13 Consider the experience of a couple who were having a Bible study, attending meetings and approaching baptism. An elder in the congregation told the man of his having enjoyed a certain motion picture. The man replied, ‘What! Do you go to see R-rated movies?’ The elder tried to excuse his actions, saying that certain of these films (considered questionable even by the world) have value if the objectionable aspects are ignored. But it appears that the man was affected. After that he progressed more slowly than his wife. Had the elder reflected on texts such as Colossians 3:2-8, Ephesians 5:3-5 and Matthew 7:12, they might have affected his conscience and his conduct.—1 Corinthians 9:22, 25-27.
In the United States films rated R are deemed unsuitable for persons under age seventeen (unless they are accompanied by a parent or guardian) because of the theme or the degree of sex, violence or profanity.
