Agnostic: a pointless term?

[Dystopia]

"I don't know and I don't care." This is the cop-out position of those who don't want to be bothered to think.

I think the concept of apatheism fits this better.

"I do not know, nobody knows, because the answer to this question is, by its nature, unknowable."

This is the Russell's Teapot position. It's the answer to theists who claim that there is a God, but that God cannot be measured, tested, confirmed or denied. A God who does not interact with the Universe in any meaningful or predictable way is unknowable. It cannot be known that such a god exists or does not exist, and if it does exist, it is irrelevant to us because it is unknowable. It may as well not exist.

You are correct, however this type of agnosticism is rarely argued for in the atheist community.

I do disagree that god's existence is, on principle, unknowable...
