Can you persuade me from Agnostic to Atheist?

[Ben Davis]

For me to adopt the antitheist stance that there are no gods I would first need to know what is meant by the word "god".

Indeed. The ignostic position is crucial, its importance can't be overstated.

If that is something out there and eternal with total causal control over everything and the decider supreme over moral matters .. then that is just ridiculous.

Once again, agreed. I find myself antitheistic (under the primary definition) for specific gods (eg. abrahamic, hindi, gaian) as there are often reasonably well-formed definitions. They may differ slightly from believer to believer but there are aspects (e.g. omni-traits, half-elephant, the world is a single organism) that are clearly fallacious and can be used as a concrete basis for opposing statements to the theistic claims of existence.

But some theists hold more nuanced notions and I'm not ready to say they are wrong.

Yep. But once again, the ignostic position applies: these gods are often so vaguely defined, in an attempt to make them ineffable/transcendent or whatever current woo-phrase is applicable, that the attempt at definition fails to provide qualifiable attributes for the theistic claims. At that stage I just have to hold up my hands and let them know that I have no idea what they're talking about. For some reason this often surprises or offends people.

So I'm just a garden variety atheist holding no belief in any god I've heard described, but not ready to render a categorical pronouncement based on so little.

As am I, in principle but come at me with talking snakes, supernatural good-luck, super-consciousnesses and the like and there'll be active opposition on my part.
