Vision and Philosophy
Prof. Sivaraj once addressed the AISCF, expressing the pride and resilience of the Scheduled Classes:
“We are the real sons of the soil in India. Our blood is pure and heart is sound. We are hard and honest workers… In this antagonism we have to seek the origin of Untouchability… the treatment of the Australian Bushman, the Negroes, and the Jews is less heinous than the suffering we were subjected to in the name of Religion, Caste and the like by the Hindus. It is slow Poisoning.”
Dr. Babasaheb Ambedkar himself praised Thanthai Sivaraj during the Nagpur All India DC Conference, July 1942:
“Indeed, a better person than him could not have been found to preside over this conference… he represents our people in the Central Legislature… and I am indeed very happy that he has been chosen to take my place.”
