Why are so many atheists in a Religion and Spirituality category?

Ok. I read your question, all of it, even the part where you tell people off for not reading it and I still didn't get the question unless it was 'atheists why are you here?' . Maybe I'm just tired but the people who prejudged your question may have simply saved themselves some reading and still got the gist of it.Ok I think I get it. You're explaining the answer to a common question not asking a question your self. Fair enough.
