Pretty much.
In a literal sense, if there was no theist (claim made), there would be no
atheist (lack of belief in said claim). The commonly used definition is the commonly one in question.
If there was never a talk of gods, there could never have been an understood definition.
I can't be biased about an un-thing. I can be biased about their followers
For the same reasons people say they aren't religious, but "spiritual". I think they like the internal and external benefits that come with concepts of "greater than me", mostly from other people.
IMO people who are spiritual are the hipsters of religion.
Think about it. When have you ever heard the phrase,
"Wow, I didn't know you were spiritual!"
They are like vegans; they make sure everyone knows, whether they asked, it's relevant or not.
(Yes, I am parodying things. Sorta.)
I'd wonder why they'd want to try and use a word that already has several definitions, some very specific, for something that doesn't fit those existing definitions.
Acknowledges ghosts exist or this redefining of "ghosts" to mean the other party's concept of "god"?
Ok, I get it.
Well, since you have established that they do believe ghosts exist, and have accepted this new odd (fast and loose) definition of "god", then rejecting that definition would be contradictory; they already accepted it, however it was declared by another party.
This atheist seems weird, as they shouldn't be hung up on merely the word "god".
That odd person's stance is based solely on their dislike of the word (and maybe personal associations) "god"; personal hangups, if I had to guess. Nothing logical in them being contradictory.
In your ghost example, you are seeing bias in the
person, not commonly standard definitions (because there are no neutral stance definitions; just definitions).
When someone says dinner, I think along these lines.
This might be dinner to someone, but I think it'd be weird to hear them say I'm showing an unintentional bias and should accept any and all definitions of "dinner".
Make sense?
I accept they call themselves that (and what that definition means to them). It wouldn't change what I perceive as "gods", in the commonly accepted definition of "gods", so I would "reject" the unnecessary redefining.
I think I see the issue. It seems like you are under the impression atheists have a preconceived idea or model of a "god".
The expectations they have should be solely based on others assertions; if gods weren't (commonly) defined with certain similar traits and abilities, there would be no expectations of what a "god" should be.
Now, atheists could very well accept or reject them because of their expectations, and not accepted definitions, but that's outside the realm of atheism.
They could also believe in the Tooth Fairy and be atheists.
If you think it needs to say more about things, I suppose you could find it lacking.
Unbeliever is probably not as popular, as it seems to have a more social anti-something aspect and most words with
un at the beginning have a negative meaning (unhealthy) or negative connotation (unnatural); like below the baseline or standard.
