For a while I believed that there was, but the more I converse with fellow atheists and agnostics the more I realise that there really aren't any points of significant difference between the two. So, atheists and agnostics, why did you decide to call yourself an atheist (not an agnostic) or an agnostic (and not an atheist)? Does your decision to stick with one label over another reflect any of the perceived differences you think exist between the two?
