Hi JGN, the idea of atheism would not be appreciated by the majority of the DK/DMK cadres as they are only against "the mythical Aryans"... and hence they would continue with Shaivism while engaging in vandalism with other beliefs of the Vedic culture...
Though they may look for succour from your words, it would be only to twist it to thier selfish gains...
But as to your remarks on the human mind, our scriptures have aptly dealt with this and it is upto us to enlighten the mind...
