Harry Potter is not just demonic indoctrination. It is an introduction to a New World Order. The Harry Potter world is very well designed. It offers far more detail about the nature of Government than any traditional Revolutionary document, like the works of Marx.
In Harry Potter world, the witches are a secret over class - governing the rest of the world in secret and ordinary world Governments are just puppets of this super ruling Class.
In the "real" Government, you will discover that not only are the no democratic elections, there is no actual leader. There is no King or Prime Minister or President - no individual responsihble for this State. It is ruled over by a self electing Civil Service which is a law unto itself.
The HP World is not unlike the real world we live in in which elected Presidents etc are little more than figureheads and the actual running of the world is done by faceless people and their ultimate plans are secret from ordinary people and the ordinary people - the Muggins are not even aware of the real situation. Even the ordinary Witches have only a dim understanding of what is going on. Either Harry Potter is a briliant satire of a serious proposal.
It is also to be noted that there is no Religion in HP World. Keith
