That isn't the original definition of the term.I looked it up, that's how I came to the definition of Agnostic: "a person who claims neither faith nor disbelief in God" . . .
Agnosticism is one of those interesting words that was coined by one specific person who explained at length how he had defined it. For instance:
"That it is wrong for a man to say he is certain of the objective truth of a proposition unless he can provide evidence which logically justifies that certainty. This is what agnosticism asserts and in my opinion, is all that is essential to agnosticism."
IOW, it originally meant a philosophical position similar to skepticism, not just being undecided.
Wrong again.And the original meaning of Atheism (as I clearly pointed out) was "a belief that there is no God" (gods)
Originally, "atheism" meant failing to follow the predominant gods of a society; Christians were "atheists" to the Romans.
In modern usage, we don't refer to any sort of theist as an atheist. I'd be willing to bet that you don't do this either, so you've already abandoned the original definition of "atheist".
... and if you are slapping the label on minority theists, then we have other issues.
