Why do you label yourselves atheists?

Atheist denies the existence of a personal god. It is a term that discribe their belief, derieved from adding the syllable "a" to the term theist. forming "a-theist". So a name was to an anti-theist. Call it a label or a name it does not matter. Call them deniers or unbelievers or agnostics, it won't make any difference.
