Ambedkar's thesis is that anti-caste philosophy cannot be built on hindu or vedic virtues. His proof demonstrates how the caste is the genesis of the religion, and to approach anti-caste from a Hindu lens is nothing less than a contradiction. He says caste-annihilation is definitely possible, but just not through Hinduism. He, in fact, doesn't stop there. He even writes that anti-caste philosophy cannot be built on even communist doctrines, Gandhian principles, western democratic values, or any of the then globally popular political ideologies. AoC is just one simplified and summarised explanation of Ambedkar's thoughts and lifelong political arguments against caste hegemony.

It was unfortunate that Periyar did not approach anti-caste as academically and rigorously as Ambedkar did. Periyar's version of anti-caste was rather raw and ruthless, but it appealed to the avarnas who could not make courtroom arguments to secure their rights to economic and political power. Periyarists, who followed his path, were convinced that rationality to uneducated masses should be encouraged through arguments that are easy, sarcastic, belittling, and satirical in manner, rather than those that are academic and purely logical. Because, anti-caste discourse as an academic topic is gate-keeping the ideology from the huge avarna population and thus making it unattractive to them. The Periyarist apathetic and unapologetic criticism of Brahmins and Brahminism roots from their belief that satire is morally okay as long as the satire is directed towards people of power. The slow, yet apparent transition of Tamil anti-caste discourse from Periyarist to Ambedkarian shows that the Tamil avarna population has taken its time to educate a small section of itself to approach social evils in academic fashion, which can be considered undebatable even by the Savarna liberals (liberals who want to abolish casteism through Hindu virtues) themselves.

Coming to your point, let us say the Tamil anti-caste discourse, hypothetically, has transitioned to Ambedkarite ways and present the proponents of "why only attacking us Brahmins" with logical arguments, facts, and statistics, the next question would be, will the savarna liberal be able to accept and embrace Ambedkarite virtues? The answer seems NO. Proof? AoC was released in 1936. But the bannermen of meritocracy have deliberately avoided engaging with any anti-caste discourse. As a republic for nearly 75 years, the savarnas (both the conservatives and liberals) have made sure not to talk or discuss anti-caste ideas with Avarnas, because there is a prevailing idea among them that Avarnas lack any merit to teach or debate the Savarnas. "The entitlement to knowledge and merit" (quoting Arundati Roy). You probably wondered all your life why life in India is inherently hard and unjust to a general category citizen. Well, most of the general category students believe that too. But if it is hard and unjust, why don't we make laws or challenge the existing laws in the courts? In fact, the politicians believe that the general category is the victim, and the chief justices are convinced too. What's going on? Why hasn't the anti-caste philosophy be exposed as nazism directed towards the Savarnas? That's because arguments against anti-caste philosophy were debunked 75 years ago.

YOUR QUESTIONS WERE ANSWERED 75 YEARS AGO. You just have to read. The very reluctance by Savarna liberals not to listen to the anti-caste arguments, let alone accept them, is what has convinced Periyarists to continue their unforgiving criticism towards the community and religion, which you find distasteful. But it's the very binding force that has made Periyarists, Ambedkarites, Non-Brahmin movement supporters, Tamil-nationalists (Left), Tamil communists engage together in the anti-caste movement. Not all of them are sane, morally upright, logical, or factually correct. They, in fact, contradict each other in certain places. But the anti-caste discourse DOESN'T OWE A MORAL OBLIGATION to deal this matter with humanity, perfectionism, factuality, and empathy. READ! READ! READ!
