I think ninja didn't target any particular group for discriminating the Dalits. The treatment we see for Dalits and lower caste is against the humainty. Any religion, be it Islam or Christanity does not teach for hating people on the bais of their castes. It relates mre to the culture of an area, which is sometimes misunderstood as religious requirements. In Muslims Syeds are respected, but Quran teaches superiority on the basis of good deeds irrespective of being Syed or non-Syed
adidravida is a caste in tamil nadu which i think is a new term (they have their local name) this people have nothing to do with adivasi or tribal religion
in my state we have chenchu/lambadi people who come from srisailam forest and other areas,similarly same people exist in central india in places like chattisgargh/madhya pradesh,orissia e.t.c
all this people are called adivasi thats why you have this moists in this states,this people think indian government is using their natural resources like trees
In
Mahabharata Drona was the guru for pandavas and kauravas. He taught them warfare. Arjuna was his fav student - being the best in archery. In the forest a low caste boy Ekalavya made a statue of Drona accepted him as his Guru and learnt archery.
Soon he became the best. The petty Arjuna upon hearing this asked his Guru Drona to demand Ekalavyas right thumb as guru dakshina.
When Ekalavya saw Drona approach him without hesitation he cut off his right thumb and offered it with humility to the Acharya.
