I get the storytelling part, actually, and accept stories are great ways to convey lessons. What I reject is the notion that because things happen a certain way in stories, we should assume they happen that way in real life. I object when we stop and don't draw the parallels between real life and the story to establish that the story is more than just a work of fiction. If you don't do that, you can "teach" lessons which are compelling (because they're well written), but just not true. Case in point, I grew up in the Christian tradition where the story of Abraham is a story about faith, trusting God, etc. Maybe I'm just not faithful enough, but if I ever hear voices telling me to tie my son up and stab him, I'm checking in to the nearest loony bin. I would instead point to the real life examples where "God" tells people to kill, and they do, and we throw them in jail or an asylum and call them crazy.
One thing that amused me when raising my own children is that for a good number of lessons in fables, fairy tales, etc, you can find one that teaches the opposite lesson. Once upon a time, I could rattle off a list of examples. My children are well past the age of fairy tales now.
