I am very much for Prakash Y Ambedkar's dream to delete the concept of 'cast' from India. To achieve that I believe the very backward lower cast people should force the lawmakers to delete the word from using. I would suggest that these lower cast people should be spelled out loud and clear as "LOWER CAST" in front of every body as UNTOUCHABLE PEOPLE. In malayalam they are called "pattiyum and poochayum" (dogs and cats) as everybody knows what it is. In most of the time it people take it for granted without a value if they earn some thing they do not deserve(ie. you are giving it for free so i can do whatever i want and i am not accountable for anything attitude).
