Dear Rajeev, I appreciate your views and description of south India in particular with kerala and tamilnadu(may be because of your ethnicity).Its a pity you did not know about other part of south India.These consitute the states of Karnatake,Andhra and maharastra.These form the integral culture of south central and deccan areas.Its because of the sacrifices of the chalukyas,Rastrkutas,marattas,Kaktiyas,Reddys and Viajayanagar kings that the entire south was protected from the onslaught of Arabs.Its because of these people the rest of south flourished great.Please have a little more study and then generalise that as south India rather than pushing only two states.
