True Anusha! We are a diverse country and most of us speak 3-4 languages. We all respect each other's language culture and traditions. I am more worried about the locals who don't have the drive to learn their mother tongue or carry it forward to next generation. There is no mandatory in education system to learn the language too. How will the outsiders learn the local language in that scenario? Unless or otherwise one develops a flair for the language the condition might not improve. There was a neeya naana talk show last year which showed how other state people had learnt so much in Tamil becuase of its richness in literature. But that is only handful.
