So what makes a dedication to Satan LHP and a dedication to Allah not LHP?
I don't dedicate anything to my gods, and I think (I know it's just a personal opinion) that's what makes someone LHP, not dedicated to any morals, actions, guidelines but your own. And not dedicated to any god but yourself.
Simple, Allah demands self-subjugation from his disciples, the Prince of Darkness does not demand worship and finds subjugation from his Initiates undesirable and even an abomination to the legacy and very purpose of his Gift.
Xeper.
