I think there are different levels of interaction.
I used to try to introduce Satanism to good people I met, anonymously, but I very often bumped into a wall as their mind refused it, sometimes with odd happenings in case of people with a natural stronger aura, I saw how their programmed subconscious reacted to anything "out of the ordinary" as an input. Then, I think people will found Satan (or be informed y one of us SS) when they are ready, or close to be ready - I think it's wise asking your own GD the level of the target person before attempting that, to avoid waste of time.
And most importantly, avoiding at all cost openly showing you are SS, because of unpredictable problems from other people may arise and slow you down, or worst.
In case we want to simply expose the enemy, it's easier as you can go by steps, many people are starting to question israel and the such, so we can put some ideas on the table here.
Also, I found there are people with a natural stronger and cleaner aura and Soul, that most likely were close to Satan in past lives and did not find Him in this life, or are on the path getting closer. Interacting with them is easier and comes more natural than many other people around.
In short, each case is different, but revealing Satanism is dangerous.
Also, many people are stubborn and too egocentric to admit your ideas are better than their old patterns, so they never admit they are wrong, and resist any change. They need to find Satanism on their own. Much better casting a spell to drive a person to Temple of Zeus website, rather than telling him/her by word. So the person will do this by his/her own will, in a way.
