I think that Nepali is indeed being imposed on various indigenous ethnicities. Once again, this just boils down to one word: choice. If you choose to speak Maithili, Bhojpuri, Newari--whatever your native tongue is--then it is your prerogative to do so. Why should Sanskrit be imposed on people as well????? How about Devnagari?? We need to protect the rights of minorities and let them decide on their own!
