How do you know Rowling isn’t lying?
I KNOW Rowling is lying -- and don't care! She's just an entertaining storyteller (aka "liar")...
And, KNOW that folks waving wooden sticks around, muttering something -- and shooting deadly bolts of colored light --is impossible.
And, I also KNOW that metal things that look like mutant flashlights can't project a beam of colored light (that stops short in about a meter) that interacts with another such beam (with lotsa spitzensparken, buzzes and hisses) -- as if it were a material, physical object -- are physically impossible.
That doesn't prevent me from enjoying (and laughing at) their descriptions or on-screen depictions.

It is the weak-minded -- who accept that such imaginary crap might actually exist -- who are in danger of being led astray by it.
Count me out.
