LOL . . . Hey, man, I'm cool with that. Besides, I am not really an atheist, so I could care less what you say about 'em. (Psst, as a matter of fact, don't tell 'em I said so, but a lot of 'em are jerks)
But I believe you are going to find it a bit difficult to make a graceful exit after lobbing that verbal hand grenade into the room. It is one thing to say something like, "Hey, so you don't like Barry Manilow and I believe 'Mandy' was one of the greatest songs ever written. I suppose we'll just have to agree to disagree." It is completely another matter altogether when you write/post an article that claims all atheists are the unwitting agents of what you believe to the be primary source of evil and cruelty in the world. That kind of claim is harder to just let pass. But we're cool, man.
