“What does fantasy literature have to do with either of those questions?”
It’s directly related.
So what are your answers?
No they are not.
Whether I am a Christian, committed or not, does not affect how I read a book about a fantastical, made up world.
Whether or not I believe that demons are real does not affect how I read a book about a fantastical, made up world.
The part you should get out of this is that HP is about a fantastical, made up world. It’s not real dude, get that through your skull. Until you can accept that these books are fantasy literature, much like Alice in Wonderland, I can’t continue this discussion. I discuss magical issues within the books as things that can’t ever happen, because THEY AREN’T REAL!
