Another reason

Ok I shouldn't have said shut up but seriously. I don't think JK Rowling sued Ultimate Book of Spells. (red head boy)

Another reason why Harry Potter isn't a rip off.
How many fundamental Christians have attacked The Worst Witch like they did with Harry Potter?

Fundamental Christians hate witches.
The Worst Witch is about witches its in the title, they will know straight away, even on book covers Mildred is riding a broomstick.

I don't think they'd care what age the book is from. They would say its teaching young children to become witches.
But fundamental Christians have never said that, they would've if they had seen the books.

Harry Potter, Bewitched, Buffy, Charmed and Sabrina have all been attacked by fundamental Christians but this never has been.

So that's the final reason why Harry Potter is not a rip off.
