The perpetual denial of Caste prejudices and the Limitations of Logic in human issues Judgement

Your denial of caste based discrimination happening even on this date is what is keeping it going. Two recent incidental, one in Rajasthan where Dalits were killed by Jats under tractor's wheels, and one in MP where the upper caste have refused clean water access to Dalits from their well -- is the most recent indicating proofs of its existence. 
     How long do you wish to continue with the domestic 'Holocaust denial' ???
   Prejudices are not measurable entities. Yet the world acknowledges the effects of prejudices on social justice. It is same as Corruption, because all corruption is done under the obfuscation of something apparently legal.
   दूध और पानी को अलग करना आज भी, तमाम वैज्ञानिक उन्नति के बावजूद, उतना ही मुश्किल है जितना पहले हुआ करता था। और बेचने वाले जानते है की पानी अकेला नहीं बिकता है। उसमे थोडा तो शुद्ध दूध मिलाना ही पड़ता है। ठीक वैसे ही, थोडा सा जातिगत भाईचारा की आढ़ में जाति भेदभाव किया जाता है। और थोडा सा कानून-पालक दिखते हुआ भ्रष्टाचार किया जाता है।
   Or do you wish to be among those who want to argue "Logically" (immeasurable prejudices cannot be logically detected of their existence, we understand) the very existence of Caste prejudices (AND of  the Corruption) once you have ascended to power ?
