Can Someone be Simply "An Agnostic?"

[One Above All]

Atheism has, like all other words, gained its "meaning" from its usage, and that usage has been that people by and large use atheism to refer to those who reject the existence of God/gods, and agnosticism to mean those individuals who abstain from assigning a truth value to the question of the divine, usually because they view it as unanswerable.

Nobody is asking them to assign a truth value to the question. We're asking them their opinion. Whether they say they won't assign a truth value is irrelevant. See my "car brand" analogy.
