I can't claim to be an expert in either atheism or postmodernism, but what I'm hearing from most of the atheists who have visited this board recently (welcome!) is the demand for "evidence" and "proof" and a dependance on scientific reasoning for the existence of God, etc. All of this strikes me as counter to what we are learning from postmodernism about the multiplicity of truths, the difference that one's perspective makes to how one experiences truth, the dissolution of dogmatic views, etc.
