Funny thing about definitions. They represent the common uses of words. They are made by the majority of the people. Now of course if it pertains to a belief held by the majority then there is a good chance that it is an honest definition. However atheists are a small percentage of the population so they do not get to place their definitions of atheism into many of the dictionaries. So it should not be surprising if those dishonest theists are at it again by defining an atheist in a way that supports their argument. It would be great if the atheist definition of Christian was placed in the dictionary. I am sure Christians would not like it at all.
But just so you know the word atheist is an old word that traces back to the Greek. It derives from a-theos. It means without god, not against god. Just as apolitical means without politics not against politics, asexual means without sexuality not against sexuality, asymmetrical means without symmetry not against symmetry.
And of course an atheist is not a person without all belief. It is a person without beliefs in god(s). Funny thing about that, just about everyone on the earth is an atheist not of course when it comes to the gods they do believe in but when it comes to the gods they are without a belief in.
It also so funny how theists just keep on presenting this stawman argument over and over and over. It is like they are bunch of ignorant idiots.
