If you're hung up on the fact that the story isn't real, it means you aren't thinking about the moral of the story. You're focusing on the wrong thing despite the fact that the insight is being spoon-fed to you...
Incidentally (though respectfully... really!), this is a textbook example of pedantry, and it's the bane of our profession.
More to the point, fiction often points to truth in ways non-fiction cannot.
