Well, I can understand why atheists want a warm and fuzzy God, one who never condemns, is accepting of everything, responds to requests as a genie would, basically, a god created in THEIR image.
Wait, why would that be inherent to atheists? I would think the believers would want that kind of god, seeing as they they think he is real. An atheist view means that you would not care as there is not a god. A compassionate person who is also an atheist might want a nice god, but its not inherent to atheism. Unless you are making the argument that atheists are atheists to get away with things.
