The Dravidian Tribes - i

The tribes in central-east India are in the news as part of violent communist struggle (Naxalite, Maoist etc...) in that region. Though a big chunk of the cadres are Dravidians, that identity has always been irrelevant. Incidentally, the leaders of Maoist movements come mostly from non-tribal Dravidians (Telugus). One more Dravidian tribe (Dongria Kondh) are in the news (for a quite sometime now) for a very classic reason. Their sacred mountain is being bought by a multinational mining company. The Kondhs are up in arms against this project. But the mountain god is not sacred just as their language. What should be the reason for the mainstream communities for supporting them? Injustice or the standard of life?
