This argument is going in circles because of semantics. Let me frame it in my experience for you. I was raised Jewish. I no longer go to temple, and I don't really subscribe to those beliefs anymore. In that sense, I am not religious. Because my interaction with the divine has shifted to that of a more direct experience, I consider myself to be spiritual. You could probably just as easily call my "spiritual" experiences "religious" experiences, but it wouldn't change the difference from the fact that they have little to nothing to do with organized religion as I've experienced it, and that it would be a hollow argument based on the semantics of which word you choose to use. These terms are ambiguous, and this argument will go no where.
