What is the proper label for someone like myself who knows of no evidence for or against the existence of a deity, but chooses to believe that there is no God?
What do you mean by "chooses to believe"? Maybe, "happens to believe"? A choice is a result of deliberative procedure, and since you are specifically stating that (these salient in the current conversation) explicit reasoning procedures were not the cause of your belief, the belief doesn't seem to qualify as result of a choice.
(See also Absence of Evidence Is Evidence of Absence.)
A choice is a result of deliberative procedure ...
When did that become the definition of "choice"? Oh dear, we may need to change that axiom in set theory. Just as well, I never really cared for that one anyways. One sock from every pair? As a result of a deliberative procedure? Give me a break.
But perhaps you can suggest a word. Not arbitrary choice, but arbitrary __. What is that word? To be honest, "decision" is the only alternative I can think of, and to my mind to "decide" sounds far more deliberative than to "choose".
I notice you don't suggest a label for my 'theological' position.
