Since atheists have a common belief system and they are pretty organized why they do not consider themselves as a part of a another religion which does not have a god?
Atheist cannot be classified as another religion. They are contradict. Religion has something on common which is belief for God while atheist is the opposite. And atheist should not be recognize. They are against God. How can you trust people with no God. They can be harmful and fearful. They do not care what ever they do.Atheist must encounter God so that their belief and mndset will ..change.
