Hi doma,
The fact that a person is a peer doesn't mean we have to take them seriously.
You can build the case for the illuminati out of the whole cloth of eccentrics everywhere. Combine that with claims about secret and gigantic piles of gold and forgeries of bearer shares and Lord Lucan sightings in Africa and it is pretty easy to see how folks might think there's a man pulling the levers behind the curtain.
Personally, I think we have enough problems on the surface without needing a subsidiary layer. Is it a surprise that crooks make forgeries? Though in this case, maybe we are looking at something on a very large scale.
On a smaller scale, the fact that someone in Nigeria keeps telling me they need help with a vast inheritance and all it takes for me to share in it is to give them a few thousand dollars upfront doesn't mean the vast inheritance exists. Right?
