Here’s the definition from your definition.com
Disbelief (lack of belief) sums it up real well. I think the second definition indicates the danger of relying too much on dictionaries for philosophical discussions.
It seems not too much to ask of someone to accept ones own label and description of belief or lack thereof. You are either claiming that I have no right to call myself an atheist, or that I must believe something I don’t, either of which is quite rude.
No one is claiming that there is no such thing as agnosticism. As I said, it is orthogonal to belief, being about knowledge. There can be agnostic theists and agnostic atheists. There can be gnostic (as opposed to agnostic) theists and atheists.
It’s really a shame that you have been brainwashed by the theistic culture into thinking all atheists are irrational god haters or dogmatic believers in no god. If you have been fooled into thinking this is what makes an atheist, I’m not surprised you don’t want to be one, but it is not true. Simply put, god is such an ill-defined term that there can be millions or billions of gods, some possibly having nothing to do with Earth. How can we ever truly believe that none of them exist? However, there is no reason to actually believe in any of them. I see that you are using the capital G God. How about the other ones? Can the theists prove that they do not exist, all of them?
Two examples: it is easy to believe that the god of the inerrant Bible does not exist, since we know the Genesis story is full of hooey. On the other hand, how can you prove or demonstrate that the deistic god does not exist? By his very nature there is no evidence of him. We can just withhold belief, not wanting to believe in things with no evidence.
Many theists, understanding that they don’t have evidence backing their belief, wish to recast the argument into one about a strawman definition of atheist. Don’t be fooled.
