Anything that is truly "spiritual" the Watchtower considers "occult" or "sorcery". Once again we can thank the Bible writers for that deception.
Babyruth made an important point. The key is love, but unconditional love. Making judgments and acting like a Pharisee is the opposite of love. If you are love, you don't worry about bad influences, they have no effect on you and cannot hurt you. So there is no need to judge, you only show love by example. Show them the way by your words and deeds. That's what's wrong with JW's in a nutshell.
