Atheism
This is an official-style thread to discuss atheism, its ideas and adherents, cultural influences, reasons for being, pros and cons of such a worldview, etc. etc.
What follows is my own personal reasons for being an atheist, as well as observations and tendencies I notice in both theists and atheists in regards to their disagreements. It is not intended to represent all or even some atheists, just me. It is, however, intended to provide many potential jumping off points for discussion. Feel free to take any of the points and run with it, or contribute your own.
As always, maintain respect and courtesy whenever possible. The very concept of atheism can be polarizing, so there is a greater need for conversational tact.

Why I am an Atheist
1. Precursors in Mythology - As I came from a Christian background, my initial doubts of theism were directed at Christianity. And littered throughout both Old and New Testaments are stories that have not just peers within mythology but precursors. Noah's Ark, the Book of Job, to name a couple popular ones among dozens of others, have stories that mirror them almost exactly in detail, but that came before the Biblical books. Most Christians see these as metaphor, not literal truth, but it begets the question of their inclusion in the Bible at all when such obvious parallels can be found in "pagan" societies. The same can be said of the God of the OT, whose decrees are sometimes flatly evil, who changes his mind, isn't omniscient at all times, and generally acts like a petulant child. One wonders how many would still have a total devotion to the Bible if they knew exactly what they were worshiping.
2. The Jesus Myth - I don't doubt Jesus' existence, but parallels and similarities can be drawn between his story and literally hundreds of others. Any mythological scholarship will point toward the idea of shared stories, motifs, and themes within savior myths and hero tales. Jesus is no different. As metaphor, I feel as though Jesus' story stands very well as a motivation and guide. As literal truth, I feel it is absurd, based on nothing but an archaic book written by superstitious and scientifically uninformed mystics and priests. Most Christians have no problem accepting Old Testament stories as metaphor, not literal truth. This is simply the next step.
3. Paranormal Void - There is a telling web comic that shows a bar graph. One bar shows the number of paranormal claims. It is huge. The other bar shows the number of paranormal claims that have been confirmed via experimentation. It is at zero. A host of physical, cognitive, statistical, and psychological reasons help explain why we often believe claims of the paranormal. These can range from the religious (exorcisms, miracles) to simply the "other" (ghosts, spoon bending, reincarnation, remote viewing, near-death experiences, among many others). But the actual evidence for them is so small as to be negligible, and the vast majority of cases can be explained by common investigative techniques or cognitive errors made by those who believe them.
4. Science as Explanation - At one point, simply pointing to the complexity and beauty of the universe was sufficient to justify God's existence. Before that, natural phenomenon were enough for people to believe in higher beings. But then we discovered fossils, medicine, evolution, plate tectonics, weather patterns, planet and galaxy formation, physics, gravity, relativity, quantum mechanics, etc. etc. etc. At best, those opposed to a scientific worldview can only poke holes in scientific theories, not propose their own viable theories. At worst, they either misinterpret or deliberately subvert facts for their own purposes.
5. The Gaps - One cannot disprove a God, which is what some people seems to believe atheism represents. I cannot claim to know one way or another, only believe. In that sense, there is an article of faith involved with either side, a word that atheists are usually loathe to invoke. However, there are varying degrees of faith. I have faith that the Earth is round, for example, though I've never seen it in its entirety. But there are valid logical and empirical reasons for me to believe such an idea. The need for any God has been reduced greatly due to the vast amount of information about the universe that we can confirm via empirical study, to the point where we even have mathematically feasible explanations of how the universe came to be. It is at a point, in my opinion, where the belief in God requires absolutely blind faith. It is this unthinking emotional justification for belief that I cannot adhere to.

Observations (again, opinions):
1. Religious Extremes - It is easy to attack the extremes: militant atheists and evangelical literalist Christians. Their beliefs and ideas either fall apart under the merest of scrutiny, or they needlessly polarize people for the sake of some agenda. It is harder to realize that these don't represent a majority, just a vocal minority.
2. Tolerance - I don't dislike or begrudge religion or the religious. I do shy away from a touchy-feely acceptance and tolerance of all religious beliefs, because there are many that I believe are harmful either on a societal/global level or individually to those who believe them. There is, however, an immense amount of good done in the name of religion, and countless people who derive meaning and strength through religion. This is needed, because not everyone can live with a materialistic worldview amenably.
3. Need for Belief - Both psychological and evolutionary studies have been released that show a profound need for belief in human beings, and how our very nature led to the organization of religions and belief in higher beings. This is not likely to change at any point in the foreseeable future. As such, I don't see a conceptual conflict between the religious and non-religious sects of the world. A move toward a better scientific understanding of the world will always draw some away from religion, but won't override our basic tendencies toward resolving metaphysical questions with a creator being. It is only when one side tries to impose their beliefs on others, either through physical violence, peer pressure, political maneuverings, etc. that I become upset.
4. Challenges to my Beliefs - Most serious (real life) challenges I have had to my non-religiousness have been emotional appeals. I don't face a defense of theism or an attack against atheism, but rather questions like "Do you feel a void in your life? How do you find meaning?" Those sorts of things. I think it reinforces my ideas of how many people relate to religion. It's a connection people feel, not something they believe on the basis of strictly logical reasoning. Which isn't a bad thing, but isn't something I can do.
5. Morality - My ethical credo is this: "Promote the happiness and freedom of all sentient beings, in so far as it does not impede upon the happiness and freedoms of others." It needs no God nor philosophical doctrine. And while in practice there can be tricky situations for any moral code, it provides a basis from which to work and a goal to which I can aspire. I believe simpler moral codes to be better, only because there is needless pain and suffering caused by absolute codes of morality that leave no leeway for an act or situation that has no ill intent or affect, but which makes people feel guilty or punishes them for their actions. Other different moral systems can be found outside of religion, as it's not hard to see an intrinsic need for morality, God or not.
6. Organized Atheism - ...is ridiculous, and probably hurts the cause more than helps. Organizations that promote the use and understanding of science and reason, however, are among my favorite organizations of any cultural genre. I have subscriptions to both Skeptical Inquirer and Skeptic Magazine, which work toward such goals, using science and reason to debunk psuedoscience, resolve conflicts within the scientific community, promote critical thinking and reasoning skills, and helping to uncover and expose those who knowingly and misleadingly profit off of the ignorance of others. They are not strictly atheist organizations, and have no stated religious belief, but I find their approach refreshing and in line with what I have discussed.
