Why does this symbol crop up on tv, in animations, commercial signs etc….? People say its a message but a message to who and for what reason? To brainwash us and manipulate us into what? I know its about the antichrist, a symbol of us being watched all the time all around the world, and apparently has lots of elite members of celebs etc….but why do we see this symbol? What is it telling normal people like us? Im so confused keep trying to research but still don’t understand. Someone help please
