"The Happy Atheist" discusses the positive side of atheism without being dogmatic or self-righeous.
Atheism can be just as much a religion as religion itself, but some of us have gone beyond atheism and theism, preferring to live our lives without wasting endless time considering questions that simply have no answers. That's what "The Happy Atheist" is, not someone who engages in relentless polemics or endless soul-searching, but someone who has decided that the question of god's existence (or lack thereof) really has no practical meaning and is not worth wasting time over.
