The lack of belief in a deity or deities. Just that. Nothing else.

Atheism doesn't hold any answers to life's big questions. It won't tell you the meaning of life and it won't tell you how it all started. It's not a religion, not a philosophy, not a way of life. Atheism is quite simply *non-belief*.
#1: "I heard you're an atheist and don't believe in God, #2. If that's true then how did the universe begin?"
#2: "I don't know for sure. The leading scientific theory right now is the Big Bang theory, but that has a few problems and might not be correct."
#1: "If there's no God then where do we know right from wrong from?"
#2: "Again, I don't know for sure, but the general theory is that we evolved this feature because social creatures do better if unit cohesion isn't hindered by constant murdering."

Atheism isn't about answers. It's not really about anything, actually.

Atheism, in fact, has NOTHING to do with Satanism. We do not all hate Christians. We're not all evil.

Besides, just by being intolerant and judgemental of Atheists, you are sinning. :)
" 'To be godless is probably the first step towards innocence,' he said, 'to lose the sense of sin and subordination, the false grief for things supposed to be lost.'
'So by innocence you mean not an absense of experience, but an absense of illusions.'
'An absense of need for illusions,' he said. 'A love of and respect for what is right before your eyes.' "

Atheism is simply the opposite of theism. The prefix A means "without" or "not", so Atheism is simply a lack of belief in god(s). It is not a religion, just like theism is not a religion. Atheists are usually quite fond of life, since it is the only one we have.Theists if you think about it, need a god to make their existance make sense and to make them respect life.
That dog is an atheist. A new-born baby is an atheist. Most of the smartest people in the world are atheists. Coincidence?

The lack of belief in a God/Goddess/gods. It does not mean that they accept science as a religion, nor does it mean they hate all others. There are prejudiced, racist, asshole atheists just like there are prejudiced, racist, asshole theists.
Christian #1: Hey, did you hear that Bill is an atheist?
Christian #2: Wow, we should all hate him, because atheism is the equivalent of believing in Satan! And Hitler!
Christian #1: No, man. He just doesn't believe in the Bible, and there is nothing wrong with that.

Atheist #1: Hey, did you hear that Joe is a Christian?
Atheist #2: Wow, we should all hate him, because Christianity is the equivalent of stupidity! And not believing any part of science!
Atheist #1: No, man. He just believes in the Bible, and there is nothing wrong with that.

There are two kinds of atheism: strong (positive) atheism and weak (negative) atheism. The difference between these two is basically that a weak atheist doesn't believe in God, while a strong atheist believes in no God.

Weak atheism is essentially the same as agnosticism. It states that since we have no proof of a God, we cannot know for sure that one exists. Strong atheism states that since we live in a scientific world where the existence of things is determined solely by their observability, we cannot assume anything unobservable to exist. God isn’t observable, therefore he doesn’t exist (cf. Occam’s Razor). This doesn't mean that an atheist wouldn't WANT to believe in God, it merely means that he has no REASON to believe in it/him.

Strong atheists often question the special treatment weak atheists – and theists – give to religion. If they believe that the tooth fairy or Santa Claus do not exist, why are they willing to give God a benefit of the doubt?

Strong atheism is often equated with religion since it takes a strong stance on the issue. This is, however, fallacious. Religion is not based on rationality, and strong atheists value rationality over fantasy. Therefore atheism is not parallel with religion.
I do not follow atheism. I merely concur with it.
