I do not understand "Atheism"

What exactly are you asking? Atheism is very simple.

Atheism, as an explicit position, can be either the affirmation of belief in the nonexistence of a god or gods, or the rejection of theism. It is also defined more broadly as an absence of belief in deities, or nontheism.

Taken from http://en.wikipedia.org/wiki/Atheism

If anything you should be able to understand Atheism very well, you practice it. You disbelieve in all other deities except for your own. Theists disbelieve in 99.9% of gods, Atheists are just .1% ahead.

(I'm assuming you're religious in some way.) Take your life, then remove religion from the equation. Voila, an atheist! McGriddles says it best, though. Imagine how you feel about Thor. That's how atheists feel about ALL deities.

Essene was a troll and is now banned.

First troll, that's an achievement.

Essene a troll? A religious flake certainly, but a troll? I don't recall reading any post of his that was offensive. Whatever.

I will still respond to the OP as if he were here. This would be a typical response to your unknown god.

Yahweh Belongs on the Scrapheap of Mythology
"I’d like to begin this exchange by making the observation that “atheist” is a term that should not even exist. We do not, after all, have a name for a person who does not believe in Zeus or Thor. In fact, we are all “atheists” with respect to Zeus and Thor and the thousands of other dead gods that now lie upon the scrapheap of mythology." Sam Harris

Is God willing to prevent evil, but not able?
Then he is not omnipotent.
Is he able, but not willing?
Then he is malevolent.
Is he both able, and willing?
Then whence cometh evil?
Is he neither able nor willing?
Then why call him God?
~ Epicurus

As you can see, atheism is not the doctrine the gentle cynic who cares not whether there is a god or not but rather, it is the existential disappointment expressed after encountering a failed theodicy.

Read the biting sarcasm, seething anger and emptiness of the ones who have experienced existential disappointment:

Religion easily has the best bullshit story of all time. Think about it. Religion has convinced people that there’s an invisible man…living in the sky. Who watches everything you do every minute of every day. And the invisible man has a list of ten specific things he doesn’t want you to do. And if you do any of these things, he will send you to a special place, of burning and fire and smoke and torture and anguish for you to live forever, and suffer, and burn, and scream, until the end of time. But he loves you. He loves you. He loves you and he needs money. George Carlin

If we go back to the beginning, we shall find that ignorance and fear created the gods; that fancy, enthusiasm, or deceit adorned them; that weakness worships them; that credulity preserves them and that custom, respect and tyranny support them in order to make the blindness of men serve their own interests. If the ignorance of nature gave birth to gods, the knowledge of nature is calculated to destroy them.
Baron D’Holbach

In regard to religious wars: You’re basically killing each other to see who’s got the better imaginary friend.
Richard Jeni

Give a man a fish and he will eat for a day; teach a man to fish and he will eat for a lifetime; give a man religion and he will die praying for a fish.
Quote from Unknown

We are afraid of the known and afraid of the unknown. That is our daily life and in that there is no hope, and therefore every form of philosophy, every form of theological concept, is merely an escape from the actual reality of what is. All outward forms of change brought about by wars, revolutions, reformations, laws and ideologies have failed completely to change the basic nature of man and therefore of society.
Thomas Jefferson

Pure atheism is the opposite of religious fanaticism. It seeks out the source of false gods and shreds these to bits with biting sarcasm, unbridled fury and finally cold ruthlessness. It seeks to snuff out the vestiges of religion so that like the German philosopher Nietzsche, atheists can declare, "God is dead and we have killed him!"

It's not just about being offensive. Most of his/her posts were aimless or rambling. Check out the Trash section to see them.
