Should R-rated movies be allowed to be shown in high schools?

[Emsworth]

In general, I think that showing films in school (whether rated R or otherwise) is utterly unnecessary. The educational content of most movies is rather minimal, especially considering their length. I don't even find documentaries particularly helpful; on the contrary, they seem exceptionally boring, and will probably be ignored by most students. On the whole, I would submit that an occasional video clip might be useful, but I cannot foresee many situations in which entire movies need to be shown.

That said, if films are to be shown, I find little justification for prohibiting R-rated films in high schools. The vast majority of high school students use profanity, play violent video games, and are familiar with sex--I don't see how a film would further "damage" them. Furthermore, the whole rating system itself is highly questionable, but that is another matter.
