You are completely missing the boat on this one.
Can i ask how?
First of all, nothing in the statement of mine that you have quoted had anything to do with me stating otherwise when it came to using "Satan" in "magic work".
It was meant as a question. You say that I am narrow-minded, but the only thing I'm trying to understand is what the archetype of Satan can be used to when you are not working with magic.
It always boils down to opinion and lack of doctrine.. but Satanism DOES have a doctrine of sorts and also it's own dogmatic practices even if that is a dirty word to most.
Satanism is not based on any doctrine, but Satanists can choose to follow one if they wish. There are also those who write their own dogma in their magical book known as a grimorie.
I would never say who are the true and false Satanists, but I don't like people who use "Satan" to attention and rebellion. They are not different from those which burn churches or killing people in the name of Satan.
The archtype of Satan, outside of magic, is used as a symbol of Man. The good parts, and also the failings of Man.
Satan the challenger, the accuser, etc.
Satan represents Man's pride, carnality, liberty, enlightenment and undefiled wisdom.
The above all fall under LHP's two primary traits:
1) Rejection of arbitrary authority
2) Respect for personal sovereignty
So, Satan, the archetype, works just as well outside of magic as it does within magic.
