Harry Potter books do not glorify occultism. I have the advantage of having read the books where as you keep regurgitating what someone has told you or someone says in the internet (who didn’t read them either).
But let me ask you this: Several people have brought up “I Dream Of Jeannie”. Did that television show glorify occultism? Jeannie practiced magic. Did the Wizard of Oz? After all Glenda was A GOOD witch!
Jeannie's dark-haired sister *was* fairly naughty, as was Samantha's dark-haired cousin Serina. When I was a teenager, I often wished I could take a magic wand to those two. ;-)
