We aren't supposed to watch R-Rated movies.
OK - this one is less about ignorance and more about willful disobedience. We have been hearing from the Prophet and church leaders on this since the '70's.
Ezra Taft Benson: "Don't see R-rated movies or vulgar videos or participate in any entertainment that is immoral, suggestive or pornographic."
H. Burke Peterson: "Now brethren of the priesthod, there should not be any X- or R-rated movies that we participate in viewing or talking about."
Man, Elder Peterson doesn't even want us to TALK about them! My discussions regarding R-rated movies consists of: "Wow, that movie looks great, I can't wait to see it. What? Crap! I didn't know it was rated R. (grumble, grumble, grumble)"
Please note that President Benson said nothing about M-Rated video games or ClearPlay. He also said nothing about NetFlix - which offers us a much larger array of movies. Because we all know - if it is R-rated in the theater, it is a no-no, but if I can get it on my TV, it MUST be edited.
