It's a well known and almost universal social taboo, and likewise almost universally reviled, to commit incest. In many countries it's even a crime punishable by jail time. However, if you ask what people think of Genesis in the Bible, you'll probably hear a far different story about their opinion of incest.
What's you guys' opinion on this? Should it be taken as an almost comical allegory, should it be seen as revealing the opinions of the day (when the Bible was created) on incest, or what?
