Tales from the internet.
Being told by an atheist that my thoughts that there are groups of atheists intent on spreading atheism is a delusion, and that in reality atheists do not form groups or have interests in common related to atheism.
Putting the Cult of Gnu aside - which is putting one hell of a thing aside - you have everything from the American Atheists to the Beyond Belief conference illustrating that yes, there are groups of atheists who have the stated goal of stamping out religion as much as they can. I used to think that atheists were only tactically ignorant about the 20th century. Apparently, they're also just as ignorant about a couple weeks ago (with an organized Atheist group meeting in Dublin, Ireland.)
