After browsing TRP for a few years now, I have observed that there are a lot of posts asking how OP can share TRP with their friend/brother/father. I too, have asked myself this question, however, you must understand that there is little you can do. I myself was tempted to show my father, who was not necessarily blue-pilled but recently suffered a major loss on his side of the family. Instead of directly showing him TRP, I handed him a copy of No More Mr. Nice Guy by Robert Glover- a socially acceptable version of TRP literature. That is literally everything you can do, the first rule of the fight club is the first rule for a reason. As tempting as it is, you cannot save anyone. You can lead by example but do not go around showing your cards to the public. You must play the game without explaining the game. If you absolutely must help someone, a copy of No More Mr. Nice Guy by Robert Glover does the trick, do not tell them about the book, physically hand them the book when you are in private, this is not foolproof, it could still backfire, but understand the risks before trying to save someone.
TLDR: If you take anything away from this post, it is that people who you try to save will often pull you under too, be careful, understand the risks.
