Someone who does not subscribe to any religions and does not believe in any gods or deities.

Strong atheism: Makes a claim that no gods exist.

Weak atheism: Does not make any claim about the existance of gods. Does not believe in gods because there is no evidence for them.
"Hey do you want to go to my church this Sunday?"
"No I am an atheist"

Do you believe in god?

Strong atheist: No, gods are just fairy tales created by man.

Weak atheist: No, there is no evidence for me to justify such a beleif with.

A person who does not believe in a deity
I don't believe in God, Yahweh, Allah (all the same deity), Vishnu, Shiva, Brahma, or any other god or goddess. Therefore, I am an atheist.

A person who doesn't believe in God, which is fine by all counts. Far be it from anyone to criticize another's religious beliefs.

However, there exists a class of atheists who can't just sit still with their own beliefs and feel they have to attack others. It is pointless, however, to convince those of religion to put aside the beliefs, as it is for Atheists to take up religious beliefs.

Essentially, militant Atheists should shut up and let those of religion enjoy themselves, inasmuch that those of religion should stop proselytizing and let people form their own beliefs. What's the point in arguing about something that is impossible to prove?
Now it is such a bizarrely improbably coincidence that anything so mindbogglingly useful the Babel fish could have evolved by chance that some thinkers have chosen to see it as a final and clinching proof of the non-existence of God.
The argument goes something like this: “I refuse to prove that I exist,” says God, “for proof denies faith, and without faith I am nothing.”
“But,” says Man, “the Babel fish is a dead giveaway isn’t it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don’t. QED.”
“Oh dear,” says God, “I hadn’t thought of that,” and promptly vanishes in a puff of logic.

Someone who believes in science rather than a god or gods.

Note: This also excludes a belief in satan. Only satanists worship satan. Contrary to christian propaganda, atheists are happy, tolerant people and except in the cases of a religon being imposed upon them, they understand the diversity of beliefs, and conseal their distaste towards religon so as not to offend others.
1. Hey, you there, other atheist! Do you ever notice how we are so much happier than christians because we don't have to adhere to stupid, self contradictory rules, have Sunday morning to sleep-in, and have the knowlage that when we die, we loose all consious thought, and our bodies rot in a coffin.

2. Thankyou Mr. Atheist, without you, there'd be no TV, cars, computers, pornography or extra-warm socks because of how much christians hate science.

3. Wow, those christians sure seem angry at us atheists. Maybe its because our science has made their religon obsolete in filling the void of ignorance from thousands of years ago, and they are scared that they have based their whole lives around a fallacy, and that we are right and they are wrong.

An atheist is, at the simplest, not a theist. A theist is someone that has a belief in a god or deities, an atheist is someone without those beliefs. To say atheism is a belief system is comparable to saying bald is a hair color or abstinence is a sexual position. There is really nothing more to the word than this. An atheist is without a belief in a god or deities.
No one ever provided convincing evidence to him that any gods exist, so to this day he remains an atheist.

Atheist-One who does not believe that God or gods exist. That's it. That's all there is to it. NEVER i mean fucking NEVER judge a whole group of people because of what some of them believe. Yes, some blindly condemn religion. Yes, some are just angry, angst-ridden teens. Yes, some say they don't believe but inside actually do. And yes, some are confused and don't know what to believe, or are just scared to. But some athiests actually CARE about the truth and have done research and personal reflection to come to a personal conclusion based on tons and tons of thought. Also, NEVER assume that you're right! No matter what you believe. Even if someone honestly believe something completely ridiculous to YOU, keep that to YOURSELF. Judging people BEFORE you really know them is parallel to racism, and people can NEVER be judged as a group. Some athiests are conceeded assholes who are so smug cause they believe they're right. But some athiests have considered the possiblities of higher powers and have actually TRIED to believe in greater enlightenment through God. I have my beliefs and that has NOTHING to do with my personality. I can have fun. I can use common sense and rationality. I think about consequences. I think about other people's feelings. I know that my reasons for this disbelief may offend you, so i KNOW that i have to keep them to myself unless asked to say why. People, you have YOUR beliefs of what you think is right. That doesn't mean you have to bring it upon other people, even if you THINK you're doing the right thing. Everyone has their reasons for thinking something, but someone's belief in their own personal TRUTH cant tell you who they are. Please, people respect each other. That's all the world needs. Respect and common sense.
Accept minor flaws, accept human imperfection, and accept people's identities. I'm not perfect. I KNOW there's a possibility that I'm wrong. Maybe some people just need to hear that.
Dude 1: Dude you coming to the party tonight?
Dude 2: Nah, sorry. Got church tomorrow.
1: Alright, man. Do whatcha gotta do.
2: Say you wanna come some time? Just so you can see what I beleive?
1: Sure, why not? I might be atheist, but who knows? Exploring the possibilities may find something that appeals to me more. It would be ignorant to just assume without personal thought that there is no higher power.
2: Glad to hear it.

(You see?! 2 people with completely different beliefs that can still be friends because they accept their PERSONALITIES over religion)
