I threw away the tape days before I ever read that information because I could tell it wasn't an allegory to the Gospel and I wasn't going to present a lie to my grandkids. And I agree that the site that had the info has some inconsistent and shaky info. I tell my kids and grandkids the truth and don't need to hide behind allegories. They don't need santa, easter bunny, or aslan to explain Jesus. I tell them the story of Jesus and they understand it. Everyone calls me crazy, but I'm not the one going around telling kids there is a santa etc... And I was raised with the santa, easter bunny junk. Sorry to break everyone's stereotype, but I haven't burned a witch in years.
So you plan on only allowing non fiction films and books into your home?
We don't do Santa, Easter Bunny, Tooth Fairy or Halloween in our home either, although we tell the stories or cultural traditions they are based on we made sure they understood that these were traditional stories. I've never understood the point of tricking children into believing an untruth. Has caused social issues when the radical children blurted out the truth to other children a time or two.
Lewis's stories are just stories, too, but they are grand stories with good morals that hint at a deeper truth. Cultural literacy is as important as history, math and science. You have to choose the stories you plan to impart cultural literacy with and Lewis is far superior to the PC crap churned out in children's lit these days.
Just my two cents.
