What I'm getting from you is a forest of non-sequiturs.
HP is pure occultims in an “entertainment” form.
You haven't produced a single bit of evidence that HP is occultism, that huge list you quoted from another site is nonsense, and you admit you haven't even read the books! And you ask what's the difference between the books and the movies? Have you EVER, in your entire life, seen a movie that was exactly like the book it was based on? Even close?
” You haven’t produced a single bit of evidence that HP is occultism”
Exactly what kind of evidence would you require? Characters engaging in commonly known occultic practices?
