Some tribes are still don't want to mingle with us. Several government and NGOs have tried to approach them but they don't welcome outsiders. The Sentinelese tribe is one of them. It's on an island in the Andaman Nikobar island area. They don't come out from their place nor they welcome outsiders. If anybody enters their island he is killed by them. An American was killed a few years ago when he tried to contact them. Another incident happened when some fishermen who landed to have rest on their island were killed by them.
When a tsunami came in the Hind ocean, one NGO uploaded their videos in which they were shot on camera attacking outsiders with their arrows and bows. I watched this video.
Be indian and buy Indian.
Thoughts exchanged is knowledge gained.
Knowledge is power.
