Agnosticism is not some sort of ‘weak atheism’, it is a completely independent thing, you can have gnostic theists, gnostic atheists, agnostic theists and agnostic atheists. It just means that you believe something can be known about the existence of god vs. you believe nothing can be known about it.
Isn’t that the whole nuance between atheism and agnostism?
