The example @Allan Paul is referring to is given when discussing man's inherent knowledge of good and evil. Bobby cites Ann Lander's response to a man who wrote to her asking what was wrong with sleeping with his sister (since it didn't seem to hurt anyone). Ann's response is an appropriate "Sick, sick, sick". To describe this example as "offensive" does nothing more than prove Bobby's point. If this example earns AP101 an X-rating then, by the same reasoning, don't let your kids read the Bible (which would earn a XXX-rating under such a rating system).
