The current concept of 'religion' as an amalgamation of spirituality and ethnic traditions (as well as political affairs in case of Islam), which is in line with the ideas of Abrahmic traditions, has probably wrongly been the central idea in our approach to world belief systems. It provides a very narrow perspective on belief systems and has been the reason for so much death and destruction in the past and the present. Probably it is the most evil thing to have occured to humankind.

It's certainly difficult for many of us to approach and explain our belief patterns in that perspective and so 'athiesm' needs to be qualified as well.  I personally prefer to see spirituality and ethnic/cultural activities separately, and for me the latter are mostly  inconsequential to be associated with 'atheism/non-atheism' though most people, notably the neo-converts and proselysers, would certainly not agree. I find most of the teachings in the Bhagvad Gita etc. fascinating and think that their 'high-level' interpretations can hardly be contested.
