@quandary,
The concept of God, as most commonly understood, is largely irrelevant to me.
I see existence as a collection of experiences, observations, interactions, reactions, and unanswered questions. I can relate much more to Spinoza's god than I can to say, the fatherly figure residing in heaven.
This does not generally constitute a disagreement in terms of the substance itself, but rather a personal lack of the need to anthropomophize.
That said, I think man needs religion, ritual, and dogma. The contemporary disintegration of traditional forms of religion have left a vacuum, where new ideologies have sprung up to fill the gaping human need. Atheism, Secular Humanism, Veganism, the Green Movement, Television -- humans will always find something to serve as their grail quest, to satiate the need for crusades, proselytizing, and purpose.
We've seen the results of "classic" religious hegemony over the last few millenia, the good and the bad. Less clear is the future-- how society will change as traditional religions are replaced by new ideologies.
While I certainly appreciate the lack of religious authoritarianism we have in the United States, I am not proud of the infantile licentiousness and increasing dependence on a nanny state that seem to be growing in the absence of traditional religious moral indoctrination.
