Is atheism a belief?

[T0 Th3 M4X]

"Atheism" originated as a term used by "theists" to specifically identify those who didn't believe in the Judeo-Christian God. Later it became a loosely used derogatory term that could apply to anybody.  You could be a "theist" and still be an "atheist" because you were an opponent to someone, but it could be applied that way to just about anything, even for political reasons or just because you didn't like someone.  Today it is most commonly used as a term that applies to people who don't adhere to a belief in any God or gods.

This is incorrect.

"Atheism" originated as a term used by the Greeks specifically to describe Christians, because they did not believe in the Greek pantheon.

That is only partially correct.  It originated long before that.  You're talking about when it was adopted as a term to describe skeptics and what not.  The orthodox believers were the ones who established it etymologically.   But then again, that was also covered at the end of my statement.  In short, "atheist" was later broadened into "atheism"  See below:

The etymological root for the word atheism originated before the 5th century BCE from the ancient Greek ἄθεος (atheos), meaning "without god(s)". In antiquity it had multiple uses as a pejorative term applied to those thought to reject the gods worshiped by the larger society, those who were forsaken by the gods or those who had no commitment to belief in the gods.[/url] The term denoted a social category created by orthodox religionists into which those who did not share their religious beliefs were placed. The actual term atheism emerged first in the 16th century. With the spread of [url=https://en.wikipedia.org/wiki/Freethought]freethought, skeptical inquiry, and subsequent increase in criticism of religion, application of the term narrowed in scope. The first individuals to identify themselves using the word atheist lived in the 18th century during the Age of Enlightenment. The French Revolution, noted for its "unprecedented atheism," witnessed the first major political movement in history to advocate for the supremacy of human reason. The French Revolution can be described as the first period where atheism became implemented politically.
