Such silly supersition is one of the many reasons why I do not take Christianity (and all other organized religions) seriously.
To trust in themselves and their own powers, as opposed to trusting in higher authority (for example, Almighty God).
Another point in Harry Potter's favor, then. I'll make sure to buy some HP novels for my niece when she gets older.
What isn't being taught is the fact that we have no powers of our own, including the power to reason.
Nonsense.
We get it from God or we get it from the Devil.
Nonsense concepts created by bronze age primitives.
Humans cannot decide right or wrong for themselves, that's the sin Adam and Eve committed.
Primitive desert nomad creation myth.
Humans cannot positively influence the world around them with "magic" on their own power, it comes from a supernatural source, God or Satan.
There is no such thing as magic.
The supreme moral moment in Huckleberry Finn is when Huck declares "Well then, I'll go to Hell" rather than turning Jim over to the slave-catchers.
As Mike Barrier said in his tribute to Disney writer Carl Bancks
When I was a child, I was in awe of Huey Dewey, and Louie, and wanted to be like them - not because they warred with their "father" and got away with it, but because they were in fact more adult than the adults in their world. Adulthood wasn't something to be scorned or regretted, it was to be achieved, and the idea was to be better at it that the adults around youThere was about a century of children's literature after 1860 which recognises that moral behaviour wasn't just following authority, but making moral choices and being prepared to act on them, even if the bad morality you were defying was set by "adults".
Rowling has rediscovered that, and surprise, kids are prepared to read about that, instead of "realistic" books about racism or gay tolerance which ape the current adult orthodoxy.
