"A"theistic: The absence of any theistic features.
And since "Theism" is defined as a belief system in God or Gods then "A"theism is nothing more or less than a complete absence of a belief in God or Gods.
"Soft Atheism" (What I call true atheism) - No belief in God / A non-belief in God. Not a belief system.
"Hard Atheism" (What I can non-true atheism; I think the proper term would be
anti-theism) - A belief there is no God. A belief system.
"Ambiguistic Atheism" - Belief in no God. A wording that blurs the division between soft and hard atheism. If you read such to be "Belief in
no God", it is hard atheism. If you read such without stressing the "no God", it is soft atheism.

Added by edit: I think there is also a softer version of "Hard Atheism". Perhaps a variety of agnosticism involving binary logic. That is, one can believe that there is no God, because one has no reason to believe the is a God. A belief because of non-belief? This belief system is not actively "anti-theistic". Kind of like the difference between a militant and a non-militent "anti-theist".
