first, i feel pity in your narrow-mindedness. diversification of race, culture, cast, credential exists in every country, Every society. The love towards your own kind is immense and it decreases as it grows to the outer circle. Take for example. If one of your neighbours quarell with somebody at your home, you take the side of your family member. If some body from another tole(nepali language) comes and quarrel to your neighbour, you take the side of your neighbour. If two villages have a football match, you support your village's team. Likewise, district and zone and region and country. when you are in America, if you see a Nepali(even if he is newar or bahun or bhote or who ever) you feel friendly. In a group of europeans, if you see an Indian, you feel more comfortable. This is all human nature. Ani etika bharma, Nepal futnu parchha bhanne wahiyat logic dine. According to your logic, India should break into more then 200 hundred parts, for it has more then 200 hundred languages and hundreds more sub classes of languages. If you think a nation should be split according to the concentration of cast and crede, UK should break into more then 1000 part. For there are hundreds of Nepali Newar, bahun, bhote living in UK. Indians haru ta thari thari tharika.People from almost all parts of the world live in London and Newyork. Should we break them in the same way? Nachahine kura garnu hunnna sathi. Mero bhannu teti matrai ho. Unification process hamro Nepal ma matrai bha hoina. Sabai thau ma bha chha. Russia ma tsar le unification process gare, France ma Napolean. Every country has their won unifier. If there was no Prithvi Narayan Shah, there would have been X. Obviously, things would have been different if so. But If means nothing. Imagine, if Life never evolved. Got my point?? I am Nepali but not the kind of Nepali you are. My mind is not that narrow to say the least.
