I always maintained that one of the suckiest things about atheism was the lack of comeuppance. While Christians can suppose I'm burning in hell when I die. I can't tell them that they'll know nothing after they die and the answers won't be provided for them because they will just die. While there does seem to be a somewhat contrary bit of comeuppance, in denying dooms days. For example a religious group has gotten enough money to advertise their judgment day as May 21st, 2011 and get some billboards up. At the very least in Hollywood where I was yesterday to see them. That's awesome.
Anybody who believes in the Judgment day is an idiot. They are stupid. Even if they believe in perfectly secular ends of the planet they are wrong. Super-volcanoes won't hurt us, large asteroids, and certainly not events from mythology like the Mayan Calendar or return of Jesus. -- Regardless if things like super-volcanoes are real and happen, the lack of comeuppance by snuffing out life before people can say "I told you so" makes things that much easier to say.
