This was very interesting, on generational change as much as the JKR controvery. This bit caught my eye:
On The Leaky Cauldron, one commenter argued against presenting “sanitized news coverage in the way the ministry and news media do in light of Voldemort’s return.” Another replied that Voldemort demonized mudbloods and muggles for not inheriting wizarding ability: “Guess who else is demonising people for not having the correct blood to be who they say they are?” Rowling gave these fans the tools they use to think about the world. Now they are having to unstitch themselves from her universe, and discover where Harry Potter ends and they begin. It’s a wrench at least as big as leaving home.
The HP books are nice little stories, but they are kid's books and not the most profound kinds of kid's books. I'm not sure they can really carry the weight these people are trying to put on them. They need to read some adult fiction, which is often more complex and goes deeper, and addresses real adult problems.
I love reading good kidlit, but it's become increasingly the case that young people don't really move beyond it.
