I consider Caste system is an excellent social format to enhance and accentuate intelligence,creativity and skills in the society. I personally believe in caste and racial purity also, to certain extent. I accept and respect people of all colours, but still have an affinity towards fair skin. Now, one does not need any computer application system to confirm, whether certain races are more intelligent or not. Brahmins are definitely an intelligent race ( I am not a Brahmin by birth) and their contributions to Indian and world civilisation is eternal and colossal. Even if Karunanidhi implement 100% reservation for ST/SC/BC, still Brahmins will advance and lead intelligent portals of Tamil and Indian society, because a legislation can not provide BRAHMINICAL CULTURE,DISCIPLINE AND ORIENTATION to reserved categories.....one needs wisdom to understand that it is BRAHMINICAL WAY OF LIFE, which gives brahmins, what they are envied at.
