It would make sense, if before movies/books/music where bought in grey envelopes without any kind of information of what you are going to watch. But there are genres, descriptions and a lot of information about what you are going to watch. Is information about dead dog more "lowering the treshold of offence" than information that the movie is stoner comedy, not holocaust documentary? Also, yes, live throws at us more, that's why we create art, partially to escape.
