Now, according to you, (and correct me if I'm wrong), you say that Atheism cannot be considered a religion because there isn't an Atheist book out there that describes how an Athiest should live; a book that would define culture, values, and/or behavior.
No. I never said anything about a book, anywhere. Although you have part of my ideas correct, adding that extraneous information suggests you don't understand all of them.
Last I checked, the definition of religion doesn't speak of needing a book or anything of that sort.
No, but it does speak of beliefs and practices, a part of the definition you continue to ignore. No amount of typing is going to make the definition of religion any smaller. Neither will it make the definition of atheism any larger. I've met people who aren't atheists who are not religious. You would take that from them. I've met atheists who are not religious. Who are you to deny them that?
This talk about governing principles is off topic and not meaningful to the question at hand. You would like to define them in a way that everyone has them, yet it is plainly obvious to me that there are people who have little or no grasp of morals at all.
This need of yours to make everyone like you disturbs me.
