apocalypto , caste system got worse and it is maintained because its advantage to dravidian parties,
like say vijayakanth is a naidu, he shouts tamil tamil tamil in all his films and finally started a dravidian party, nobody accused him of starting a telugu party now suppose karthik joins the forward block , it is projected as much as possible as a maravar party , this weakens their support from others. same with sarath, he runs a so called nadar party, this strategy is effectively used to weaken tamil political leaders even in national parties like congress , so kamaraj was framed as a nadar leader wherever possible. there have been so many attacks against setc buses and theatres in KA, and nobody was arrested but in TN hundreds have already been arrested for protesting , no dravidian will allow others to attack another dravidian, to hell with tamils !!!
