In ordinary conversations, people like to tell funny or shocking things to laugh or keep the conversation going. Even if you tell the bare minimum about what JoS is, without going into details about jewish curses, Hitler or aliens, people will already be able to use it as an interesting "crazy" story that will sometimes be shared.
A person who worships Satan is already interesting information, and if he also believes that Satan is an alien, magic exists, Hitler was right and much more, this story will be imprinted in his mind not with a blunt pencil, but with a bold red marker.
And they will share it unconsciously. For them, it's just an excuse to keep the conversation going, but for you, it can be a floating mine. Information can go from person to person until it gets to someone who can use it to harm you. You won't have an idea about him, but he will have. This information can also lie in someone's memory for a long time and come up decades later.
The only correct solution to this problem is not to talk too much about yourself.
If you want to tell people about JoS in order to help them, then do it ANONYMOUSLY and in Internet, observing everything for your own caution. This way your reach will be hundreds of times greater and you will not have to carefully study whether a person is suitable for accepting such information or not. All the worthy ones will see the materials you distribute and come here, the unworthy ones will stay for a while or just pass by. There are very few worthy people in our time, believe me.
JoS insists on anonymity as much as possible for a reason. The consequences of de-anonymization in this area may not be fully seen, but it can be very dangerous. Good luck.
