Refer me to one atheist who denies the existence of God.... Etymologically, as well as philosophically, an atheist is one without God. That is all the 'A' before 'Theist' really means.
George William FooteAtheists are often charged with blasphemy, but it is a crime they cannot commit... When the Atheist examines, denounces, or satirises the gods, he is not dealing with persons but with ideas. He is incapable of insulting God, for he does not admit the existence of any such being... We attack not a person but a belief, not a binge but an idea, not a fact but a fancy.
