[Suzerain of Sheol]

I haven't been following it too closely, but I believe I read that the guy behind this "prophecy" has been getting criticism from Christians as much as from any other group.

When it comes down to it, religion is just window-dressing for the delusions that give these sort of people a sense of meaning in life. There have been similar movements in the past that haven't been tied to organized religion. The need to be more than a speck of dust floating in a sea of nothingness is a powerful psychological motivator, and for some, the apocalyptic conclusion is the only one.

If you want to see the silver lining here, at least the Dispensationalist/Rapture movement is largely non-violent. It could be a lot worse.
