In my opinion it is as it usually is with conspiracy theories....absolute hogwash! I compare the stories about them and the almost lustful eagerness of people to believe in their existence with the fascination people have and had for cheap trivial literature or in earlier times so called ’penny dreadfuls’ (cheap horror stories for the amusement of the masses) or even the fascination with news spread by the so called yellow press.. The concept of the Illuminati as a secret society angers, upsets and most of all frightens and scares people. They feel helpless and explain their everyday troubles by blaming the alleged illuminati. Nothing more than a scapegoat concept. Has always worked, works always and probably will always work. There might be elitist circles, powerful lobbyists and the like, but I definitely do not believe in an all seeing all knowing all controlling secret society. Have a great day :)
Is it verified? Is it confirmed? Apparently not. It remains a theory, and was never proven. Those popular people just state they are members of Illuminati as a joke.
