I hate to be the one to break this to you but....."Religion" by
definition is "the belief in and worship of a god or gods, or any
such system of belief and worship." Any other definition is a
derivation of this definition. In other words if one "exercises or
reads religiously" The usage of the word is meant to invoke the
adherence to a practice so strict that is mandated by a deity (in
other words, the one true definition). So, in short, you cannot have
a "athiest religion"! At least not in reality!
Furthermore, a belief need not have any factual basis. It is a
misnomer to say that "one beliefs in reality". For example, the
reality is that the world is an ovoid sphere. You can choose to
belief it or not but the fact is irrefutable. It cannot be believed
into being flat, by any amount of religous or pseudo=religous faith!
You are entitled to believe in anything that you wish, even that
atheism is a religion or a belief system (which it, by definition
cannot be,since it is a statement of reality). You do not have
so "seek reality". You are surrounded by it, encompassed by and part
of it! Those who believe that some omnipotent, omni-benevolent,
omniscient being or beings exist simply to care-take over man kind
have to "seek-reality" in the madness and make believe world they
have created.
