Hard to evaluate the Davis thing. Hard to find any reliable sources of info on these guys, since, as Njorl noted, the mainstream media has pretty much ignored them for awhile. If true, is he on drugs or just dumb? Obviously hasn't considered the past history of Moon.
I think the media's grown kind of bored with Moon. 20, 30 years ago, he had a pretty close relationship with the president of S. Korea and a South Korean lobbyist. The church's foundation went beyond just Moon as the second coming. It also spelled out the role of NKorea (and its evil parents, China and the Soviet Union) and SKorea (and its good parents, Japan and the US) in the battle over whether good or evil would triumph in the world. The Moonies have always supported very conservative, anti-communist politicians and seemed to almost be an offshoot of a plan to ensure a large amount of foreign aid to protect SKorea from NKorea. It got a little bit of media coverage, since its membership practices were definitely cultish - give up all your money to the church and help them raise more money; convince your parents to send you more money that you can give to the church; etc.
The president got assassinated and there was a big congressional scandal over the money the lobbyist was distributing. Moon kept his church going and used church members as cheap labor for building up a small financial empire, which seems to have grown over the years. I think the issue of using the church members as cheap labor got them a little bit of media coverage, as well.
After the end of the cold war, I would have figured Moon would just be happy to rake in the profits from his companies and his cheap labor. I guess you still have China and NKorea to worry about, though.
I would think any serious politician, right or left wing, would keep as far away as possible from someone so out there on the fringe .
