Camping is always wrong, be it in the woods (bears crap there), First Person Shooters and in Eschatology.
Still,the world ends from someone's perspective everyday (You might even say that The World Ends With You. Yes, I just bought up a game title in the Off-topic thread section!), so for those who die today or tomorrow, as far as they know, Harold Camping was right.
Live with the knowledge that from someone's point of view, he was right, no matter how very wrong he is about the Rapture and all that jazz just as Camping might have to live for another minute or two with the knowledge that he was wrong (perhaps not for the final time in his life).
It's almost too bad that none of the 4 Ponies of the Apocalypse will show up tomorrow. A lot of people around the Escapist forums will be devastated, I'm sure. How sure? As sure as Harold Camping is that the Rapture will come tomorrow.
In other words, I'm dead wrong and proud of it for some reason.
