So, J.K. Rowling is more observant that we give her credit for?
She is extremely observant and wary of big government, and the books are extremely good!
Her books are subversively conservative --- ineffectual government officials "protecting" you being one of the big themes; followed by the MSM-is-a-bunch-of-lies (the "Daily Prophet" being the newspaper); wand control merely disarms the good-guys.
Etc.
There was an excellent article on NRO about Rowling being an "Inkling" --- that is, a Christian writer who weaves Christian themes and symbolism all throughout her books.
