My goodness--what a fabulous opportunity for parents to--scary thought--actually talk with children about the difference between fantasy/dreams and reality--and to remind the children that they (the parents) are there to protect them. I suppose the folks opposed to Harry Potter fantasy are also opposed to Santa Claus and the Easter Bunny. Leaves nothing to the imagination, literally.
I take it you are in favor of repeatedly lieing to your children. I think this says more about yourself than those you lash out at.
