very sensitive issues indeed. how irony; even after 250 years of unification n formation of modern nepal, after many initiatives taken by past rulers who tried to inetegrate all these nationalisties or ethnicities or castes under one umbrella through religion and nationalism; mahendra's policy of 'one state, one lang n one costum'; it still is very hot n sensitive rather still unsolved. this proves ones race, culture, dialects, religions, etc r self identity and precious for which one can opt for extreme measures as to safeguard, protect, continue n expand it. in case of nepal, such system should b drafted that acknowledges every ethnicities and thier differences as possible; ie fairness. current solution as per our leaders r federal setup with possible auotnomy becasue centralised government system failed utterly to address such sensitve issues. but they r yet to come up to conclusion on which model to b slected for federal set up, either by ethnicity n lang or by regions or mixed of both. activists of various ethncities r pressuring gov for this cause only not for seperatism, racism nor r they xenophob in nature except for sum opportunist fanatics, like when the conflict was instigated between pahadi n madhesis. apart from that i dont think any groups r threatning or giving ultimatum to any other differnt group to leave or declaring vedetta upon them. like khas r demanding for khasan state but they havnet declared non khas to leave thier area, likewise tharu r demanding for tharuwan but again they havnt declared rivalry with non tharus, same with khambuwan n limbuwan it is just demand to name the state initiated by the same people but thier doctrine doesnt say non kiratis to leave or face hostility n likewise.

 after sucessful declaration of republic the competency of this gov will b proved if they could sucessfully solve this very sentsitive ethnicity problem reasonably to the best interest of every people n nation as a whole.
