Really, all these adults overthinking everything. I read all the fairy tales and other stories where they all had happy endings when the hero married the heroine and so did my DC, but I cannot remember any of us ever taking any message from them, especially about the role of women in real life. They were stories, fantasies, nothing to do with our lives.
The only message I ever got from a book was from Swallows and Amazons and that was that sailing was great fun and I really would love a chance to do it. When I got to university, I promptly joined the sailing club and as I expected loved dinghy sailing.
As a child, I cannot ever remember reading a book that related even slightly to my life - and I was a voracious reader, not even Swallows and Amazons and I certainly did not use any of them as role models.
Where is the evidence that children's, or adults attitudes to the place of women, or men is affected by reading fairy tales or any other fiction?
