Don't change the subject. We are not talking about ignorance, we are talking about whether one is a theist or not a theist. Having taken a stance or not having taken a stance. It's just between those two. We start off not theists, not believing gods exist. Then when we learn about gods we can take the stance that gods exist but until then we stay not theists as we always were.
I didn't change the subject. The claim was made that atheism was the default position and I made an argument against that claim.
What is the purpose of claiming that atheism is the default position? The purpose is to support the idea that atheism is not a position, and that one is just naturally an atheist, without any effort taken by the atheist.
But is an atheist, like yourself, truly in a default state?
A baby is not a theist because he is ignorant of the subject and incapable of forming a belief. You are not a theist because you have rejected the arguments for theism and find atheism to be more rational. These are two very different positions. The former is an unconcious default state of being. The latter is an active choice.
How can an active choice be a default state?
You cannot label all cases of "non-theism" as the default state because they aren't all in a default state. It is false equivalence to conflate the two.
