Unfortunately, not everyone accepts that all languages equal. Hindi speaking people think that their language is somehow superior and more than equal than others. They squander money on celebrating Hindi divas, have you heard of the government celebrating other languages? It is this step motherly treatment that is causing resentment and it also plays into the hands of Hindi speaking people who end up inculcating this sense of false superiority over non-Hindi speaking Indians. The govt. should rein in its excessive love for Hindi and give equal treatment to all Indian languages.
