Does telling children fairytales make them irrational?

Next he will be suggesting we stop children playing "Lets Pretend" games and dressing up as pirates, cowboys/girls, princesses etc. as this doesn't prepare them for the real world. Let's leave children the magic of fairy tales and Father Christmas.

Adults have been telling fairy stories to children since time immemorial,
and I don't think it has done any harm.

I loved fairy tales when small, as did daughter and as do grandchildren.
R Dawkins is promoting a new book I believe so something 'controversial' helps perhaps?
I have noticed the 3 bears and any wolves look friendlier in most new books than the illustrations I remember from my old books.

I can only speak personally of course, but for me they just used to be literally 'fairytales' that I enjoyed but had no bearing on my life.Looking back on them, some are very dark subject matter, but I don't remember being scared by them. As you say , they may well be subtle lessons in life that we take in without realising it, not sure really.I wonder if children still like hearing about them?For me as a child, it all seemed 'long ago and far away.'
