At the same time, politicians like Karunanidhi who gives inflamatory statements has put their daughters in KA, their MPs speak Hindi in parliament and he himself writes Hindi poetry. However, when it comes to TN everything changes. It is tamil all the way. Again nothing wrong with that, but why to thrash other cultures, why not to accept people from all parts of India and why to force them to speak in Tamil when they are in Chennai.
Now that you have started it, Tamilians, you are getting the return of it. It will not go away. First change your outlook and come out of the well. As N. Karthikeyan (from TN) tells "Tamil society is a closed society".
