The only cast problem that existed was untouchability. You are just making alegations against the upper cast. You dont have any proof for these alegations. Britishers and anti-nationals like Periyar, Veeramani, Karunanidhi, Nehru etc. have spread these rumours and your just use it to divide the Hindu community. Only people like Stalin(sone of Karunanidhi), Son of Veerapandia Arumugam(who died of AIDS) rape so many girls and escape.
