The point they're trying to make in regards to America though is moderately valid. The difference in sexual attitudes is dramatic between the USA and Europe, and what offends individuals here or at least seems in bad taste, isn't elsewhere. (I seem to remember opening with that point too...)
Just as some people in the USA want to steer our country toward a removal of sex from most situations for the sake of professionalism, other places in the world have achieved professionalism inspite of pornography as well.
Japan is a prime case in point, with standards of pornography that shock most people here. Yet they are undoubtably very professional in a business setting, and have come to be one of the modern standards of business conduct. Japan also has very few problems with sex and violence, despite similiar levels of exposure.
One point that bears a great deal of thinking is that the connection between sex/violence and dark behavior is worst in the countries that have the most issues with pornogaphy. In the USA, the statistical correlation is stronger than anywhere else, and for the most part, the more liberal the sexual tendencies of the nation in regards to the media, the more the strength of relationship decreases. In Japan the issue is almost null and void, with the correlation being insignificant.
Maybe it's time we stop teaching our kids to fear, repress, or hide sex. Maybe it's time to stop thinking sex is cheap, and must be kept private, that sex is something we CAN seperate our everyday lives from. Food for thought.
