Nepal Constitution should prevent forced change of mother tongue

According to the 2001 National Census, only 0.47 percent people in the country spoke Hindi language. People speaking Maithili, Bhojpuri, Tharu and Awadhi stood at 12.3 percent, 7.53 percent, 5.86 percent and 2.47 percent, respectively. But, if the various Madhes-based political parties have their way, Hindi speaking people will increase to more than 25 percent in the new Constitution.

Several Madhes-based political parties have issued a circular asking the Tarai people to register Hindi as their mother tongue instead of their actual mother tongue. I wonder what the response of the non-Madhesi parties will be to this request? The new Nepal Constitution has included provision to prevent 'forced conversion of religion'. Perhaps, provision to prevent 'forced conversion of mother-tongue' should be included as well.
