Harry Potter, of course. Oz had absolutely nothing to do with the occult. The story did make fun of sorcery in a way, but the message of the story was socio-political. The 'gifts' given to the tin man and the lion were shown in the story to actually be within their true natures.(as in Oz was shown to be a fraud, and a charletan.)
I'm referring to the whole series, not to the book that was made into the movie. The Wizard becomes more deeply involved in magic in subsequent volumes, there are many magical folk who use potions and the like. there is a magical belt, magic pearls that give wisdom and strength, and evil nomes that can be vanquished only with eggs. (The latter is clear support for abortion rights.)
Not true. Baum and his wife were practicing theosophists.
Baum's mother-in-law, Matilda Joslyn Gage, was a radical lesbian feminist who traveled with the Baums and influenced them daily. Baum said he even named the main character of his later books, Princess Osma, after Gage: Matilda Joslyn Gage.
This from the horse's mouth...
There's a much darker story behind the green curtain than most people realize.
But, hey, they're just words. And as we've been told, words have no power, right?
