"No, the definition of atheism is the abscence of theism. A = without, theism = belief in a god or gods. Atheism = without belief in a god or gods. I do not believe in any deities, therefore I am an atheist."

If you were to literally translate from Latin, you would be correct.

But the meaning of the word 'atheism' is not equivalent to the literal Latin translation.

You may want to learn about this before you proclaim yourself as an atheist.

If you are "without belief in a god or gods", then a more fitting term would be agnostic. That is, "without knowing". Meaning that you do not commit yourself to the affirmative belief in the existence or the non-existence of a god or gods.

If you get to tell me what it is to be an atheist, do I get to tell Christians what it is to be a Christian?

If you are "without belief in a god or gods", then a more fitting term would be agnostic.

No, I'm not agnostic. I believe that if a god exists, it is possible to know that this god exists -- depending on the nature of said deity. An agnostic believes that it is impossible to know whether or not a god exists.
