It seems that agnostics and atheists are defind by the majority, being thiest, and not by ourselves. As a result we often fall in line to their theology. This is why I am so adamant that we use the term atheist in order to normalize it so that we can define it.
As atheist we simply do not believe, it is like a light switch, you either belive or you don't.
Agnostics may be questioning what or who god is. This is good as they are using reason to question thier beliefs. They may belief in many things. My mother believes we were planted by space aliens(It will take more time to explain evolution to her, and that its real). With agnostics there is going to be many degrees of belief. This is to be expected. It is our job as athiest to simply help them use reason so that they can sort it out on their own.
