I think I'm now an ignostic, Atheist now. Damn identity crisis. Good comments on this thread.

I’m a naturalist. I don’t believe in the supernatural and leave it at that.

Yes! I have been thinking the same thing. Never heard the term "ignosticism" before.

Never really thought of it this way. Someone says god to me; I think of a synonym for fictional friend.

none so blind as those who will not see

There are probaby as many beliefs(definitions) of god as there are are believers. Just getting one that unifies the major religions would be impossible in my view.

Karen Armstrong made a good effort in her book called "The Great Transformation;.
The World in the Time of Buddha, Socrates, Confucius and Jeremiah"

Having studied the history of the four major movements she shows they all do have a connection,depsite originating separately.
In a nutshell they all came to the conclusion that the Golden Rule is a common goal,if only the adherents would stick to just that principle the world would be a far better place. You need no other rule in my view.
Whatever your god or non belief, it's something all views can actually agree on. We should start defining what makes a good human being from that end rather than trying to define the other end (an undefinable deity.)

I think it's a valid position, but not mutually exclusive with atheism (defined here only as lack of belief in God or gods). However, most theists have a particular concept of God or gods they believe in, so I think we can use those more specific cases to move away from ignosticism except for the most general notion of God or gods.
