Ambedkar’s censors tried to excise his Vedic critiques and planned conversion from the lecture

Evidence

Besides that you have more than once stated in your address that you had decided to walk out of the fold of the Hindus and that that was your last address as a Hindu. You have also unnecessarily attacked the morality and reasonableness of the Vedas and other religious books of the Hindus, and have at length dwelt upon the technical side of Hindu religion, which has absolutely no connection with the problem at issue, so much so that some of the passages have become irrelevant and off the point. We would have been very pleased if you had confined your address to that portion given to me, or if an addition was necessary, it would have been limited to what you had written on Brahminism, etc. The last portion which deals with the complete annihilation of the Hindu religion and doubts the morality of the sacred books of the Hindus as well as a hint about your intention to leave the Hindu fold does not seem to me to be relevant. — Ambedkar, B R, Annihilation of Caste_ The Annotated…, 778
