To be agnostic in the sense of "I don't want to get involved" or "I am sitting on the fence" is not a tenable position. It is incomplete in that it begs for a follow-up. However, most of those claiming an (operational) agnosticism are implicitly pointing out to a (philosophical) atheism.
Otherwise, only "sitting on a fence" would implicitly recognize a certain region bounded by that fence.
But there is no fence.
And here is the zen.
