Yes, on the question.
It's muddied, on the parenthesis clarification part.
If an atheist dilutes commonly used and understood terminology and definitions (the ghosts-god one), then I don't think he could honestly call himself one; sounds like having your cake and eating it, too.
I suppose similar to the way one would discern a legitimate belief in a person.
Personally, I think "discerning legitimate belief" actually gets involved in True Scotsman territory. Even attempting to judge by actions, choices, statements, it's alluding to what beliefs may or may not be held by a person. It's still not directly letting you prove the "belief" is there. This is all assuming that a belief falls under the category, at a minimum, of a conscious mental construct of some sort.
I mean, James can say he loves Stacy, marries Stacy, remains faithful to Stacy for 10 years, claims he believes he loves her and wants to be with her. Then one day he wakes up, realizes it "was all a lie", changes his mind, "I never loved her," etc and so forth. Was the belief ever really there, or was denial in it's place instead ? So personally, I would say "discerning legitimate belief" is basically not objective.
Unless I'm attempting to delve deeper into the foundational reasoning behind someone's claim of being whatever-they-claim-themselves-to-be, if someone says they're an atheist, fine they're an atheist. Same with Christian or any other similar label. Even if the person is running around a statue of Godzilla saying, "Thou art a holy god !" and then in the next breath claiming to be an atheist ... whatever, if you say so lol

I mean, I could probably try and dig deeper and reveal some cognitive dissonance and intellectual dishonesty, but if they are convinced they identify with that, then that's their story and they're sticking to it. For whatever reason. Similar with the Christian.
Say if a Christian believed, solely based on reading the Bible, I would say it wasn't legitimate; using that logic, whatever religious book they read determined their belief. And I wouldn't call how they arrived at that as "legitimate".
I may not be getting what you're saying here in this paragraph. If you'd like to expound, cool ... if not, cool as well.
Most atheists I know are very critical of people calling themselves atheists who hold contradictory type claims.
I think identity is important to people, and those who take it seriously enough to attempt to classify themselves and/or draw a line in the sand, typically seem to take some kind of pride in wanting to make sure that those who bear the same title pass muster in their eyes. Political/religious/social affiliations, etc.
One one sense, being an atheist could be seen as a harder and seemly untenable "belief" to hold, because of the simplicity of the essence of the "statement" and its arrived-at-conclusion baggage.
YEC - Christian
Evolution - Christian
Faith - Christian
Works - Christian
Hell - Christian
Spirit crystals - Atheist?
C'mon now...
I would point out just now that your statement here suggest that being an atheist, in one sense, involved holding a belief, not the lack of having one ... which brings me back full circle somewhat to my original digging with my post in the first place.
Interestingly, I don't think it's so much the statement that the term "atheist" makes which has a lot of baggage, it's the way that conclusion is often arrived at which has the baggage. It is a rather simplistic statement, very reductionist ... but the implications are where the "baggage" is at. It reminds me very much of e=mc(2). I remember in calculus, one of my teachers gave me a problem which I began to work on, and it took me about 30 minutes to solve ... and when I had finally solved it, as I was writing out the solution, I realized I was writing out "e=mc(2)" and I got shivers down my spine. It was surreal

The implications of how the concept of "atheism" is often arrived at, in a reductionist type of way, are somewhat similar to me.
Concerning atheists and spirit crystals lol ... dude I've known atheists who believe in a lot more than ghosts

I know one who believes in a complicated and complex history involving spiritual entities that exist in another dimension alongside ours. What they didn't recognize or believe in, were deities and "gods" of any kind.
Something interesting I find amongst many atheists who start to tag on all these attributes that "true atheists" should have, and generalize, is that they tend to presume most atheists come to their conclusions and belief stances based on critical thinking and skeptical inquiry. "We atheists use critical thinking and science," etc and so forth. It's a pet peeve of mine somewhat when I see all these extra generalizations being poured onto "atheists" by atheists themselves that has nothing to do with the definition of atheist, and then those very atheists want to argue with me that all atheists fit a type of mold or stereotype. It's like arguing with believers. "We atheists think ______," and "We atheists believe ______" ... Atheists need only share one thing in common and one thing only, but try telling that to certain types of atheists lol ...
I will admit though, I have yet to meet an atheist who STILL believes in the power of crystals ...
