This type of thing bothers me a lot..... I used to think that at least South India is a very well behaved area, and only thing can happen there is Islamic Violence. Now I am surprised to learn this type of infightings. I heard in Karnataka there are large population of Kannada people of Tamil origin, as they settled in that area long time ago. They may speak Kannada but they are ethnically Tamil, and sometimes they speak both. I happen to have worked with such a guy. I don't know how they would react to this type of nonsense... Friends, please think India first...and behave as the way Netaji once told "When U meet a fellow desi, always greet him by saying Jai Hind". By the way I am from the Lost State of India Waste Bengal. your friend Sanatani
