I think your just bringing up Racial issues, when you talk about racial conduct there cant be a positive or negative side, Because there are good and bad people among us all, Muslim to Singhala, Tamil to Christian, Only the values have changed, So Please dont Racially discriminate The Sri Lankan Racial Concent. Anyhow I would say Singhala is the national Language so we should all learn it, which is anyhow thought throughout Sri lanka, but now its changing as for futuristic purpouses The lankan government has given English as a 1st classification of language to conduct studies, which currently some schools teach * government schools. and eventhrough Malaysia doesnt use Tamil as of not one of there main Languages, Singapore does addopt it as one of there main languages, the Tamil Ethnicity.
