Ok, change my view. Quoting him directly, “I believe that caste has saved Hinduism from disintegration. One of my correspondents suggests that we should abolish the caste system but adopt the class system of Europe, meaning that the idea of hereditary castes should be rejected. I am inclined to think that the law of heredity is an eternal law and any attempt to alter it must lead to utter confusion. Hindus believe in transmigration of the soul and Nature will adjust the balance by degrading a Brahmin if he misbehaves to a lower caste, and upgrading one who lives the life of a Brahmin to a Brahmin in his next life.”

He believes in hereditary inherited caste apartheid. Any wiggle room in his words there?

I guess you are right. But that isn't going to reduce the role he played in India's Independence movement or the momentum he gave to the formation process of independent India. I will argue that the strength he gave to the peaceful formation of the republic later on facilitated the anti caste movements by later politicians in independent India.
