Simple question: Can you believe that god(s) exist and still be an atheist?
If so, please explain your position.
If not, is there any other belief which would also disqualifiy you as an atheist?
Simply put no. The atheist belief, and what makes them atheist, is their belief, that they are lacking in a belief, that a deity exists.
This means everything associated and related to a deity, for to accept something like tarrot cards as one example, the perceived atheist would be giving support to the possibility of a deity position and thereby diminishing their lack of belief position. They would be moving to or from the pagan position, or caught between two belief patterns.
Other than the above, the atheist position is open slather to every other belief pattern on earth, the good, the bad and the downright ugly of it all.
