Yes it seems that SRI LANKA did **** up by banning basic rights like
1)circulation of magazines,newspapers,movies of tamil nadu
2)Trying to change the demography by planting sinhalese in tamil majority areas
3)banning the citizenship to tamils of indian origin in 1948.
4)banned tamils from going to study in india
5)a sort of quota based system that adversly impacted tamils
6)sinhala official language act of 1956 made sinhalese as the national language and tamils who were fluent in english and tamil suffered as a result but in 1987 tamil was indeed made a national language
7)destruction of jaffna public library in 1981
HMMM.................******* lankans need to get their act together,,,we should have conquered them
