Actually I feel a big issue need not be made. North Indians always faced brunt of attacks from invaders for the last 1000 years whereas south generally had indian kings who were in general popular with the people. May it was the vindyas which protected the south and powerful kingdoms like Vijayanagar, cholas, cheras , pandyas, chalukya, rashtrakootas which at various points of time provided a benovolent rule. The common people of the north resisted individually the cruel taxes and cruel regime in their own way by carrying out small struggles and violating the cruel rules of these ruler. Probably it is the same defensive mentallity which still persists. This may go away after one or two generation. Proper education at an young age for respecting rule of law can handle this situation. Let us not start a north vs south fight here.
