I think the problem in your perception is illustrated by the underlined word. If you had said glorified magic I might agree with you.
In my opinion, Rowling wrote a book with witchcraft and magic as a plot element and background. But it is likely the philosopher Pogo was correct in his assessment of where we tend to go wrong. I can just see him surveying a picnic ground after the crowds have left, and saying,
"We see what we bring with us."
Have you read Larry Niven's story, "The Magic Goes Away"?
I suppose if the magic were used as allegory, or even as satire, I could see the subject matter being in the hands of someone conservative. I am just bothered by her depiction of all non-magical people as clueless sourpusses.
I know, the book is supposed to be fun. And granted, there are evil magicians, like You-Know-Who, and the existence of the “Dark Arts.” But in general I was bothered by what the alternative universe of Hogwarts represented: Diversity U, with Dumbledore as president.
