Duality in the Organization

Dan, a friend of mine, who challenged that I was spiritual but not on the Tibetan Buddhist path.  It struck me that this statement is wrong on so many different levels.  Even within a spiritual organization where its purpose is to help one to transcend dualistic notions, a sense of us vs them arises.  At the heart of buddhism is the pursuit of noble truth, this is the pursuit of truth which can free the human soul from suffering.  Yet Dan's comments isn't concerned with whether I was stating noble truth only it wasn't truth that he knew of in the Tibetan tradition.  It is disconcerting to see the notion of wanting to be "a good Buddhist"; this notion only reinforces separation, and secularization of a true spiritual life.
