No, it's not an exaggeration. An exaggeration is an overstatement, more of something of the same kind. No matter how much wind you gather together, two or more Bobs in the same place, a hundred or a thousand Bobs, an infinity of Bobs do not a single deity make. Only vasty amounts of hot air. There is a difference in kind.
That is the important point, Bob. Calling the wind "god" is an exaggeration. Therefore I am asking you where or how the use of "god" anywhere isn't also such an exaggeration. How do you know that when you say "god" it isn't an exaggeration and confusion of being(s)/things(s) into something much beyond what it/they are?
One uses the word "god" when one is talking about a "god," a Baal or a Ganesh. This is not a confusion. There are perfectly interesting things about both gods to be said. Hermes as well — I'm very fond of Norman O. Brown's book on the subject, Hermes The Thief. There is neither confusion nor exaggeration involved here. When using the word "God," with the capital, you will get differences between speakers, and ambiguities on the matter concerning the existence of God, but the concept is reasonably clear to most native speakers of English.
If you want to suggest that 1) "god"; or 2)"God" is an subject exaggerated and confused beyond what it should be, you've got a discussion about theology on your hands. You could well take either side. The discussion is one that will in the end rest upon belief.
But, short of turning the question into a discussion on theology, if you take care to talk about god when the subject is god, and God when the subject is God, one with the capital and the other without, it's not a question of exaggeration, is it? What would you be exaggerating? Wind? Grass? Onions?
Additionally, these would be not only confusions of size, but confusions of kind as well, a confusion of the part for the whole, at least when one is, presumably, talking about The Nameless. In other words, I believe that one would have to work fairly hard to fail to distinguish God from cantaloupe, Bromo Seltzer or, Ta-Da!, Art.
A few recent thoughts on the matter, at any rate.
All my best, Bob Kaven
