In the movie rating process, some of the biggest determining factors are and nudity, violence, and profanity. Even if a movie is suffused with profanity and violence, which are serious "cancers" in our society, the worst it gets is an R, whereas if a movie has a significant amount of or nudity in it, it's in line for an NC-17. , usually, is a natural process borne of love, or at least good feelings, whereas violence(I include in this category because the only way that and are alike is that the same organs are used) is not, and is, I believe, more detrimental to be shown, and therefore should receive the higher rating.
