A cranky and rather poorly educated man, who powered a movement that was curiously reactionary. A reaction against a certain kind of elitism which did characterize South Indian high culture
Someone whose rhetoric became "dated" in his own lifetime
Politics of Reaction can stem from the so-called "progressive" side as well
Though Ambedkar was better educated and intellectually a more "serious" figure than "Periyar"
E.g. Gopal Krishna Gokhale, Jawaharlal Nehru, maybe even MK Gandhi
Ostensibly he claimed to be a champion of reason, science, , the English language etc
But his reactionary side blinded him to the fact that it was indeed the "elites" who he was revolting against who best embraced these so-called vehicles of "progress"
While many on the Right would like that to be true, the reality is tradition has many sources in Indian society. And its sustenance is not entirely top-down
It was his own people (the subalterns of different hues) who were more conservative and "hidebound" than he'd have liked
The elites he reviled were ironically embracing "change" and "modernity" (for better or worse) more readily and rapidly
Because it didn't reflect the ground realities. The reality being that the gulf between the accomplishments of V1 and the rest in Tamil society was driven more by forces of modernity than by sources of traditional authority
