He has addressed not only to an individual citizen of India but to a representative of citizens i.e. the people of India.
Dear Mr. Ram Samudre,
You are right. I respect your principle. A citizen and moreover the people of India are supreme and most honorable.
But, where is point to object Mr. Assumi ! Has he said that a citizen or people of India are not supreme ! Has he used the word "Honourable" for a non citizen !!!
He has not addressed an individual citizen but a representative of citizens i.e. the people of India. It is good thing to respect the people's representatives. They are collectively citizen of India.
