NRN is not an elected representative, he is not an armed forces officer, he is not a beauraucrat, he does nor represent the nation and he is not a leader. His choice of words are his personal matter. If a homeless urchin libels the national flag or anthem on the streets, none of you would care to even interfere, would you? Why would you then when someone like NRN does it, he does nor represent you nor the nation. Mind your own business. And its definitely not a question of north vs. south, hindi vs. english, bengali vs. kannada or whatever nonsense you want to attribute to it.
And yes, he is an achiever, I salute him for whatever he's achieved, things that all you (and me) have not even attempted.
