I used to see his posts on religous threads for months and a lot of reaction to them, not with any facts, just emotional reaction. This sort of thing attracts me. I want to give the theory a good airing and see if someone can come up with somthing concrete to refute it.
There are too many things that make sense about it and too much political upheaval in the world based on it's absense in truth. That is to say, I figure the world picture would be dramatically different if the theory were generally accepted, and for the good of all in the world. But certainly NOT for the Arabs and Islamisists. That's another attractive feature.
I will not drown in tears if it turns out to be false. I'm grafted anyway. But it is true, well, a lot of things on the world scene can be explained.
You can't have read too many LostTribe replies. I particularly liked the little dancing figure and the (ggg) replies to objectors. His main proof seems to be that he's visited the British Musuem, whatever that implies. You might be more concerned in trying to dig up any evidence of his claims. This would require a great deal of work.
