Personally, I find it kinda amusing when atheists, who believe they will completely cease to exist upon death, are 'threatened' with an afterlife, albeit a miserable one.
I dont believe that any true atheist fears what happens after death...apparently they believe that is just the end of things, and for many, that simply does not frighten them...when they start believing in an afterlife, they are no longer atheists..as least that is how I see it...
Sitting on a cloud, wearing a halo, and mucking about with a harp might be fun for hours at a time. If we're talking about eternity, I'm calling it Hell.
The Almighty isn't a sadist. Atheists simply cease to exist. There is no "punishment" or any sort of retribution. God is a class act; He doesn't act like some snubbed two-year-old.
I'm kind of amused by people who think threats are a good substitute for argument.
