To say "there is no god" is to posit a belief (can't be proved one way or another, even if def. of "god" didn't range so much as to make it a hugely problematic concept to attempt to communicate to another).
I agree with that.
I still consider aethism more & even other than a disbelief in god. Aethism, to me, is a recognition that a belief in God can be detrimental, esp. when people organize such beliefs into dogma or formal religion.
