Do you have the right to be an atheist?

[ErGingerbreadMandude]

If you are saying that "A lack of belief in god." is Atheism.
Then Pool comes along one day and says that Pool lacks a belief in atheism.
Seeing how Theism is no longer existent.
Where the burden of proof now?

You lack a belief that, I lack a belief in a god, in a world where the concept of god doesn't exist? Lol you have no idea what your even talking about, and for the millionth time atheism still makes no claims.

Yes,i understand atheism is not making any claims but is simply rejecting the claim proposed by theists.
In the scenario presented by you there is no longer theism which would mean that theists are no longer making a claim.
So you're just sitting there rejecting a claim that isn't even made.
That makes you the one making the claim.
