A) To express an position, you must first be aware of such a position. That is self evident.
Non-sequitur. A dog may not realise it is a dog or have any concept of an animal kingdom existing, that doesn't stop it being a dog.
Some sentient being that has no concept of God is 'non-theist', 'godless', 'without God'...a.k.a a-theist. There is no imperative need to introduce a knowledge of the subject/choices.
B) No I have not...that is an assumption or misinterpretation on your part. I have clarified this enough already..I made no such limitation..in fact quite the contrary.
You stated it as a legitimate definition here...
So, basically unless you are an atheist...in the definition that a God doesn't exist as a definitive
Animals are not atheist or theist...you cannot reasonably apply anthropomorphic philosophical positions to non-humans who have no way to express them.
Theism and atheism are binary, you are either one or the other. There are lots of concepts animals don't understand but it doesn't stop them being so. A snail has no concept of a backbone, it doesn't stop it being an invertebrate.
It's like saying a rock is atheist. Its pointless....
It being pointless doesn't make it any less true.
I am not introducing it..it is inherent in the philosophical position. You are either misreading or misrepresenting the position of being active...the active part is the ability to express the philosophical position coherently. The 'lack of belief in Gods' is the simple position of not agreeing with the Theist, so thereby a common definition of Atheism, and the one you are trying to express is a lack of belief in theism....by definition an active position.
You are trying to argue that an absence of something is the existence of something, it's not. As has been explained to you with the analogy that not collecting stamps isn't an activity.
For it to be inactive you would simply 'lack belief'..there would be no active knowledge of Theism or its related concepts, and I have yet to meet or hear an Atheist define their atheism just as a 'lack of belief' without defining the belief to which the lack applies....I would say that would classified (if it can be classified at all) as agnosticism.
That doesn't disprove my position though. I'm saying anyone that has no concept of a God or gods is by definition an atheist
AS WELL AS people [you describe] who know of the concept and choose to reject it. Something or someone that has no concept of God also has no concept of Atheism but, again, that doesn't mean they aren't one (see dog analogy above).
