I think this is a mess we made up for last 60 years.
We threw English and made Sinhalese as national language.
Then there were so many problems for minorities so we gave a prominent place for Tamil language as well.Cool then we had examinations and everything in Tamil and Sinhala.
Now government doing same for Anthem and expecting there are doing such a great thing for Tamils. Actually Tamils do not want a separate anthem, there are a lot they want such as water, infrastructure, education and other facilities. Meanwhile TNA only wants federal.
