***Mirrors aren't vehicles of magic in HP, some mirrors are enchanted, ***
They are used as a method of "seeing" adn alternate or symbolic reality which is really divination.
***They aren't ever used in HP in any way that ever resembles any of the various real world occult rituals that use mirrors. ***
Mirrors are use in occult magik for a number of puroses. I'm sure you don't know them all.
****I find the very presence of condemning Christians to be the ultimate insult ****
Care to point me to where I condemned someone???
And if "condeming" is so bad - then why are you condeming me???
Two big falsehoods, there's no "they" with the mirror your discussing, it's a one of a kind item that shows a person their greatest desire; and that's not divination, divination is trying to find real data ususally from the future, the mirror in HP just shows a person what they want most in the world. And it's a very dangerous mirror and is eventually destroyed because people tend to get addicted to the "perfect" world they see in the mirror. No occult there.
Mirrors in the occult are primarily used for divination. Which isn't what the mirror you're talking about is used for. More stnadard magic mirrors in HP are basically video phones, also totally non-occult related.
You're saying the books lead people away from Christianity, that is condemning, and false.
