I would rather watch a R, or even a X, movie that is depicted as fiction or for entertainment purposes than watch some of those washtowel videos that are just as scary and depict death threats for anyone that slacks a bit. They don't want adults to watch horror or porn movies that are entertainment, yet they show small children as young as babies death threats to keep them bound to the religion and going full blast.
And, what if I watch it in a foreign language? If I wish to learn, say German (or Sanskrit, but that is a bit less common in movies), I can watch movies that I enjoy (regardless of the rating) and pay attention to the words. As much as I can read something like Alice in Wonderland in German, I can also watch something that is X rated and they would not be able to understand. And then, I would be able to describe it, in the foreign language (after I get more proficient), so they would not be able to judge what they cannot understand. Many people in North America do this to learn Spanish or French (though those languages are common enough so finding a hounder that can understand them is not a problem).
