Why do you think it is a conscious choice?
Do you have to reject religion to be an atheist?
Think about what Dawkins said about children and religion: It doesn't make sense to talk about Muslim children or Christian children. They are children of Muslims/Christians.
He doesn't call them atheists, either.
I think this
is a semantics issue, and it's partly to do with the way I see other people apply the 'atheist' label (as though it's equal to religion in that it's the decision to disbelieve as much as religion is the decision to believe).
I don't like 'active' atheism myself, and see it rather as the absense of something (which would of course make the baby an atheist), not a 'thing' in itself. However, the word is often not
used that way, particularly by the religious. So, without knowing the reason for the question in the OP, then I am assuming he means it as the 'active' definition (as that, in my experience, is how most people refer to it).
If EGarrett would like to clarify what he means by atheist, then we can debate the issue on the terms presented. At present, we have none.
I didn't imagine for a moment that the baby was his, as he referred to it as 'that'. But if it is, then congratulations to you EGarrett.
By 'conscious choice', I was talking about the application of a label. We've made a name for something and be bestow upon ourselves or those who fit the definition.
