No, I don't "not believe in them." I simply don't know of them, so I don't know whether I might believe in them or not. Ignorance and disbelief are two completely different things.
They're both encompassed by "not believing". "Not believing" is the complement of "believing": unless you believe, then you do not believe.
Once again: an "ism" is a cognitive exercise that requires higher thinking. Babies are not "apolitical." They're babies. Why? Because they're not capable of being political in the first place.
That doesn't mean they aren't apolitical; it means they can't help but be apolitical.
If I can't do something, then this implies I don't do it.
Yes, it is. Belief or not is a choice, because both stances are the same cognitive function.
yes it does. Do. The. Math. The value of "empty" might be 0, but it's still an assignable and understandable value that defines "empty."
The emptiness still has a value, and, as such, is not a "default position." If you've never seen the box, you don't know whether it's empty or full. if you've never heard of deity, you wouldn't have any grounds to either believe or disbelieve.
"Lack of awareness" and "lack of belief" are two different things. That's why we have two different terms for them. Atheism is a lack of theism, not a lack of knowledge of theism.
I'm not sure if I don't get the concept you're trying to express, or if you're just wrong.
It seems to me that you're contradicting yourself. If atheism is a lack of theism, then anyone who is not a theist is an atheist.
Just as it's impossible to disbelieve something you've never heard of. and that's what atheism is: disbelief in the concept of deity. If you don't know the concept, you can't disbelieve it.
Try applying this to adults and you'll see the problems with this approach.
There is no single "concept of deity". There are actually
uncountably many concepts of deity, and they often contradict each other. Rejecting belief in one doesn't necessarily imply rejecting belief in the others. For any given person, there are many concepts of deity that they will never even hear of. There are others that a person might hear of, but only hear explained in an incoherent way.
How is an atheist supposed to reject all of them? Merely rejecting
some of them isn't enough: even the vast majority of theists do that much, and if our approach implies that theists can be atheists, we end up with nonsense.
All of us are as unaware as a baby when it comes to the vast majority of god-concepts that humanity has believed in. Despite this, we use the word "atheist" to describe adults who haven't even considered all those god-concepts that they've never heard of.
If you're going to say that this lack of awareness disqualifies babies from being atheists, are you going to say that lack of awareness disqualifies adults? Because adult atheists are just as unaware of most god-concepts as a baby is.
