I don't think so, please. Right?

Atheism defines itself by what it is not, rather than by what it is.
Oxford Dictionary; Atheism is the disbelief or lack of belief in the existence of God or gods.
In that sense, Atheism is like a reflection in a mirror, with almost any religion a resource for Atheism's own defining reflection. The main mirror appears to be Christianity, since Atheists spend the most time, differentiating themselves; fixing their face, near that particular mirror.
If you are looking for the best resource about Atheism, get a Bible and believe in the opposite. I have known many Atheists who are quite knowledgeable about the Bible, using their detailed knowledge, as the mirror to describe what they do not believe. It is quite a bizarre religion.
What is interesting is the radical Left in the USA, does something similar, with President Trump being a good example of their mirror. Trump is a unique person with a loud personality. The Left were trained to hate President Trump, so much, they will do and believe the opposite of what Trump does or says. Even the policies of the radical Left are like a mirror image of Trump's, without any regard to practical utility; illegal immigration, or without any regard to any positive unifying goal for all, like Make America Great Again. Instead this is reflected as America is evil and the Constitution is obsolete but with no good replacement in mind besides Big Brother Socialism.
Hate appears to play a role in creating this mirror effect. Hate can cause a data filter effect. The classic example are two lovers going down with the ship unable to see the love they once had. All they have is the hate. Psychologically, it is similar to forming negative stereotypes; one sizes fits all prejudices, which are big on the Left. The White Christian Male is evil, so do the opposite; DEI, via that mirror, or be hated and persecuted with the perceived injustice of the mirror, without regard to utility.
Atheism may have formed through hate and prejudice stereotypes, hate the Church, that eventually morphed into a full length mirror, to help itself to grow and recruit new members. There are now more gods, not to believe in, than ever.
As an interesting morphing example of the Atheist mirror effect, can be seen in the new fad of gender. Transgender only represents a small fraction of all people, say 2%. The majority; 98%, are based on biological sex. The majority is being described as more homogeneous and linear; hateful parents predators, with only the 2% transgender fluid in the sense of gender; victims. This is recruiting new young members, since there is no nuance in the majority; mirror. The reflection appears to be more open and Progressive.
It appears the original recipe of Atheism is being copied, as a tool to manipulate impressionable minds. The added difference appears to be the manipulators are creating their own trick mirror; fake news, misinformation and propaganda. Like gossip, they plant untrue seeds to form their mirror; misrepresentations. The naive minds reflect within this alt realty mirror, they think is real. The effect is like a double negative reflection, that appears to add to a positive. However, that positive is a delusion, from a reflection in a trick mirror. Atheism, although a reflection of religion, does stick with the facts of religion. This new morph is not about the facts, trick mirrors, which are harmful to all.
One good analogous way to look at this contrast, between defining oneself as a positive, versus defining oneself by what you are not, is to look animal species. A distinct species is self sufficient as to what it is. It has it own self identifying nature and habitat. It is not trying to be what it is not but rather is what it is.
Defining oneself by what it is not, is like being stuck between two species. On one hand, can sees themselves as being different, but only by what they are not. There is still connections to the original. One has not yet become a new species, but are still exiting from the past like a missing link. Evolutionary data is deplete of missing links. This would suggest this missing link state is an unnatural state, according to the data that supports evolution; fossils. Either species clicks or they disappear; quantum jumps. It is ego will and choice, that is able to sustain this missing link state; knowledge of good and evil and the Shadow.
