Everybody has slightly different rules regarding this. Mine are:1. Do they practice Christianity, Islam or Judaism or do they have Jewish blood? Don't tell these people anything ever, under any circumstances.2. Are they are materialists, naturalists, or atheists? Personally, I can't stand these people and wouldn't tell them anything, just for that reason alone. 3. Find out how they feel about an occult topic of your choosing that can't be connected directly to Spiritual Satanism and see how they respond.
Its not really a matter of being open or confident. It has to do with your safety. Their is also the matter of skill level. Someone skilled in Black Magick isn't going to tell someone new about it because their are things that require skill here. And I imagine some people are more private simply because they don't have the tolerance for stupid invalidative nonsense from barely conscious pond scum.
As you can see there are very practical reasons for keeping ones mouth shut. The time to be open and honest is when you are with a Demon. And when you meet other Spiritual Satanists you can trust.
