From a rationalist point of view, however, an absolute statement indicates absolute belief. In a subject such as Theism where there is no "proof", an absolute belief in any direction can only be attributed to "faith" (and/or fallacy), which many will agree is the defining quality of a religion. In other words, if you assign 0% probability to the possibility of theism, as the word atheism suggests, then you are making a statement of faith, and so, are imitating a religion.
Technically, a rationalist could only ever call themselves an Agnostic due to the implications of Faith associated with the word Atheist. However, the word Agnostic has it's problems as well. Namely, the term suggests a variable degree, but with the subject of religion, where no proof exists, it is impossible to define this variable. Sure, you could call yourself an "Agnostic of an undefined degree" and be right, but that doesn't describe a person very well at all. You can't draw any conclusions from that statement, and so it's pointless to even mention. Titles are assigned to people as an indication of what they are likely to do. When you ask someone what they classify themselves as, you are asking how they are going to make their decisions. In such a case, the title Atheist may only mean "A person who will make decisions as though there is no god/religion" whereas "Agnostic of an undefined degree" (which is the only proper answer a truly rational person may give), doesn't say anything at all.
You may be able to call Atheism a religion rationally, but it's the only word that can mean anything when describing a person who will make decisions as though there is no god/religion. In other words, you're stuck between practicality and technicality.
