The Geminian offers this spiel:

Is Atheism a Religion? A simple question, In order to answer the question, we must be sure we understand the question.

What is Atheism? A precise and undebatable definition of Atheism is required in order to move forward, so let us define it.

The word Atheism can be broken down easily in two parts: A-, and Theism. The first part, A-, is a prefix meaning "not" or the absence of, without, lacking. The second part, Theism, means a belief in the existence of a god or gods. Conjoined, the word Atheism means:

A lack of belief in the existence of a god or gods.

The word religion comes from the Latin word religio, which means: the service and worship of God or the supernatural ; a cause, principle, or system of beliefs held to with ardor and faith

Is Atheism a religion?

Let us superimpose our definitions unto the question.

Is Atheism, (the lack of a belief in the existence of a god or gods,) a religion, (the service and worship of a god or supernatural?)

There is an obvious contradiction here.

Can one who lacks a belief in any god(s) existence, serve, worship, or have faith in a god?

The answer is no. Atheism is not a religion. Religion implies theism, it requires it. Theism does not imply religion, as one may have the belief but not serve or worship.

To say that atheism is a religion is also to say that all humanity has a religion. The word Theism applies only to humans, Atheism, by definition applies to anything that doesn't believe. An Aardvark lacks a belief in a god or gods, but does it have a religion?

To say Atheism is a "belief system" is a contradiction, as belief system requires belief, and atheism is the absence of belief.

Part of the confusion may come from the chronology of the two words: Theism and Atheism. Theism was defined first, later the prefix A, was added to create a new word. This chronology creates confusion in that the word atheism sprang from the word theism, but in fact, historically, theism sprang from atheism. Error occurs when one supposes that atheism is a choice, a choice is an active assertion, this is not the case, to believe is active. Theism is an assertion by an individual, it is a choice, one must subscribe to a belief. Atheism requires nothing, no choice, no assertion. Every baby born is an atheist, they lack the belief, later they make a conscious choice to begin to believe,(this includes Jesus.) Is is ironic that theists look upon atheists as "dissidents," because it is the theists who broke ranks and distanced themselves from atheists, this is also required of each individual theist at least once.

Atheism is not a religion.
Theism is dissention from the norm.

These two assertions are inarguable.
