Funny how Fairiests have a definition of an A-Fairiest without actually asking the A-Fariests if their definition is what the A-Fairests actually affirm about the question of belief or non-belief in the existence of Fairies.
As an atheist, let me give you my perspective on this label your organization is pushing for you to believe without actually asking someone like me:
There is no “-ism” to being an atheist because there is no dogma, leaders, texts, unifying world views, political views, etc. It is a single position to a single question. You can literally be any world view and be any religion and be an atheist as well because the label atheist is only to be applied to someone who is not convinced yet that the supernatural realm exists. Example: Comic book nerds geek out over their favorite comic book series just as much as religious nerds geek out over their favorite scripture. Do they really need to believe that spiderman actually exists to enjoy the Marvel comic series? No, no they don’t.
The first word of this definition gives away the biasness of this point of view. “Denial”. It presupposes that atheists believe there is actually a deity and are just denying its existence. No, we actually don’t believe its there just like we don’t believe spiderman is there.
Methodological Naturalist Atheists, like me, are not declaring that we know this for certain though and we do admit the logical arguments are apparently sound for why someone would believe that the supernatural is there. However, until reality actually demonstrates that the supernatural is there, then it’s not to be used as a reason to explain anything. Just like how I can replace the word “supernatural” with “magic” and all the religious arguments still work. Still doesn’t mean I can use the idea of magic as an explanation for anything in reality. Once we can actually demonstrate that magic is part of reality, that is when we are allowed to use it as an explanation for something. Not a moment sooner. The logical arguments for magic / supernatural are a good reason to look for it, but its not there yet until we actually find it in reality in some way. There is currently zero actual evidence of the supernatural / magic in reality, it is all just logical argument. And that is defining something into existence.
