Aspiration doesn’t come into it; you’re either “not theist” (i.e. atheist for any etymologists out there) or you are - you don’t choose or aspire.
An atheist is not theist but atheist doesn’t mean “not theist”.
Atheist Noun 1. Someone who denies the existence of god.
It’s more like ((A theo) ist)
The A negates the god then the is says its a person that does that.
Agnostic Noun 1. A person who doubts truth of religion.
And agnostic ((A gnosis) tic)
The A negates knowledge of god, I presume the tic suffix makes it a person.
An agnostic is not a theist but that doesn’t make him an atheist.
I really don’t regard playing such silly semantic games as intelligent. Just a boring waste of time.
