Atheism is a theistic position.
I asked ChatGPT about this, since it is a "large language model," and ought to know something about language. I asked: 'If atheism means "lack of belief in deities," how can some people claim that atheism is a "position?" I mean, isn't it more of a "lack of position" with regard to gods?'
Here is ChatGPT's response.
"That's a great question! The distinction between atheism as a lack of belief and as a position can be nuanced.
"On one hand, atheism can be seen simply as the absence of belief in gods, which might suggest a neutral or passive stance. This perspective emphasizes that atheism is not necessarily an assertion or a belief system but rather a rejection of theistic claims.
"On the other hand, many people consider atheism a position or stance because it often entails a worldview or a philosophy that actively embraces secularism, reason, or skepticism regarding supernatural claims. In this sense, it becomes a more defined perspective on existence and knowledge, even if it doesn't posit an alternative belief system in deities.
"So, while it can be viewed as a lack of belief, it can also represent a conscious decision to reject theistic claims and embrace a secular viewpoint, making it a position in its own right."
It would seem to me, then, that atheism by itself is not a "position" of any kind, unless it is paired with some other position or philosophy. A person who doesn't believe in any gods, but who is uninterested in making society "secular" or doesn't care at all about what anybody else believes would not be holding a "theistic position" at all.
