Yes its true that North indian are a bit more manipulative that is very wrong. But violence is very bad, Destructive and Anti Social.
.Though North India are not good in many aspect. But their contribution towards India in very significant. What Raj will tell of Good intellectuals of North India (IAS, Engineers, and Doctors) and Hard working labours. If people of other place have capability they will get important positions. and will not Cry like Raj Thakre. Its survival of fittest. If North Indians (Bihar , UP) will go on strike all activity of India will halt. But if Marathi will go to strike nothing much will happen. Raj Thakre is feeling insecure and his future is very dark. Though he may get cheap popularity and vote. He should have motivated Marathi for progress. This is shame for Marathi.
Original citizen of India are Schedule Tribe Only. So Leave India to Schedule Tribe.
