Nepal will not split because of cultural differences. Nepal has come to this stage maintaining high diversity since Lichhabi period and there was never a communal conflict. Every conflict that occurred was for the throne or for the post of prime minister. Hard core Muslim country's experience doesn't apply to Nepal. There is caste system of course for the old generation but the new generation doesn't give a crap about it. Even in old generation when have they fought to the extent that another can't exist side by side? Having differences is to be human being because everybody is unique individual. If all persons were the same replica then what's the point of having another person. Even the fingers in the hands are not same length but when they join together the fist is made which gives all the strength to the hand. Everybody likes the attention. These political scientists wrote to create the controversy based on the circumstances surrounding them. And another one refuted the same way but from another perspective. These debates might have made them reach to the height of only popularity they could get but the truth is something else. After all, nobody recognizes them who don't make noises.
