Are there dearth of old widows in society? Whom are u kidding with that claim? Rajaji didnt resign cos of Periyar alone. His downfall was because of his Hereditary education policy which every Tamil hook and corner opposed it.
Periyar had a way of high handedness resulting in split. He suspended and started protests as a joke against the British. Anna had already fought with Periyar on the issue of "Black Shirts", and Anna as a mark of protest, wore an overgrown black shirt at a public meet.
How can u tell other religious societies didnt have that kind of nonsence? Have Islam, Christianity eliminated caste in Tamil Nadu? A big Lol for u. Why didnt he fight for rights for Muslim womens? Cos he was expecting favors from Jinnah.
The Anna-Periyar showdown is folklore in Tamil Nadu. Annadurai was in shadows of Periyar, not able to oppose him at those period. When people saw how Periyar started behaving high handedly, DK split up, majority "ditched" Periyar, their own leader. During their Dravida Nadu demand, even Tamils deemed it as a joke. There was virtually no movement for independent Tamil Nadu. Majority Tamils were with INC, Justice Party, IML and there was 0 demands from Tamils from those parties. Instead Tamil people were actively involved in independence movement of Independent "Bharat". DK dont represent Tamils, nor Karuna.
There was a reason why Anna is considered way above Periyar. A true, humility gentleman. Padikaada Medhai.
I do not know what is ur agenda. But if u think Tamilians are for separation from India. (Karuna would have looted TN as a separate country with no checks from other Indians) Then u are wrong. And u will be wrong in long distant future.
