The late Rohith Vemula was a student of Hyderabad University. He was a Dalit so was duly harassed by the Upper Caste university officials. The matter went up to the Central government and he found injustice from there too. Perhaps he should have become more engaged in the university's Ambedkar Study Circle or he should have become engaged with the Left. In 2016 he chose to commit suicide by hanging in a friend's hostel room.
The matter became a cause celebre for quite some time that year and the next few. I too attended a protest gathering in his honor at my city's town hall.
Right in 2016 his mother and brother chose to adopt Buddhism in Bombay probably partly in protest and partly in desire of a better life without rampant discrimination.
India is quite a disharmonious society, with or without the complaints of Muslims.
What has any of this to do with Hindutva or the churn in India since the BJP rook over.
Dalits getting educated at all is a big thing in the civilizational sense.
It's not as if he would have been a upper caste under the Congress.
Be serious.
Cheers, Doc
