Hindi speaking people will not understand the problem of non-hindi speaking people because in the hindi belt everybody speaks only hindi and they do not entertain any other language. You do not face this risk of losing your language and culture. Hence you don't understand this paradigm. And whichever place they go to they ensure others speak to them in Hindi. They generally do not converse in English. They feel they are nationalistic and Hindi is the only true language of India. Hindi speakers should understand that Hindi is not Hindustan. To be truly Indian and appreciate Indianness you need to come out of your "Nothing other than Hindi" mentality.
