Agnosticism IS the most dishonest position

[Belacqua]

When people use the term god, are they referring to my definition or the one that they have in their own minds ?

Probably they are referring to the idea of God that they have. 

When people use the term "game," are they referring to their own meaning, or mine? Definitions vary. Does this mean that "game" is meaningless?

When I say the word is meaningless, that is exactly what I mean.

But that's not what "meaningless" means. For a term to be meaningless, there has to be no meaning. For theists, it has a meaning. 

There are no values that you can place upon the word because those values cannot be demonstrated.

What do you mean by "values cannot be demonstrated"? Do you mean that the referent of the word has to be proven by science to have a meaning? That would be begging the question.

It's like asking "How many angels can dance on the head of a pin ?"
How many imaginary items that have 0 mass can you put upon a finite space.
Answer - "An infinite number of nothing."

The question about angels on the head of a pin was never used by any theologian. It was made up by people who wanted to tease theologians. 

It is true that some philosophers believe there can be things with no extension. Ideas, for example. 

That is god. An infinite number of zeros that all add up to zero.
That is meaningless.

Aristotle defines God as actus purus. The term actus purus has a meaning. Many Christians agree with the meaning. Therefore, the term God has a meaning.
