"Rapture": Utter stupidity founded on nonsense

Rapture Letters claims that suddenly, soon, all the people who believe in (their flavor of) "god" will die and those who don't believe in their flavor of "god" will remain. The silly part is that many people are looking forward to being killed by their "god"!

It would be laughable but for the fact that 40% of the people in the USA have this delusion.

So the Rapture Letters web site is devoted to sending letters to the sane people who don't believe in god(s) after this supposed mass murder has occured. The example letter includes a magic incantation which if uttered by a survivor will supposedly cause them to die instantly too.

Could anything be more insane?
