To the person who said in India, an ethnic group with 17% of population will have to learn majority language in India. What bull***t. In India, Tamil, Telulu, Marathi, etc about 5 to 7% and one can live in India (and many people do) without knowing Hindi because there are many official languages in India. In fact, 17% is Tamils but 27% is Tamil speaking in SL because it should include the muslims.
Please don't insult India. We believe in equal rights. We have tried hard and still trying to make sure every ethnic group in India feels part and parcel of India. This is what makes India great.
