Bhikari-
On the few questions that you have raised..
What do I want the Bahunbad Samaj to do?

Creation of a multi-ethnic political environment that truly reflects the multi ethnic Nepalese diaspora.
It is surprising how this question of "coming together" sprung out of the wilderness with the abolishment of the monarchy. Birendra's "peace zone" sanctuary prevailed as minority representation was non-existent, and political and military environs were the domains of the Khas. By the 1980s the well oiled Khas propaganda machine was at its peak with Gorkhapatra and the state run NTV, the only forms of mass media churning out Khas biased propaganda while the education ministry proliferated a linear form of history in books that we all thought were true. "Bir Nepali Sena" of our history books who bravely fought the British were Khas and did not represent other ethnicities. Moreover, with regards to Nepalese independency from the British India Company, contrasting versions of have been researched by writers during the Rana Rule who claim "Nipal" to be a semi-protectorate very much in the manner of the Aden protectorate. Onley states in his book, The Arabian Frontier of the British Raj, that Nepal was a semi independent state and therefore a protectorate of the British depending on the East India Company for military and economic aid. Therefore, it seems very obvious that the notion of Nepal's independency seems to be hilariously a propaganda product of the Khas and has suprisingly prevailed to this day. This notion of our independency from the colonists is so entrenched in our psyche that any suggestion that it could be otherwise would be inviting outrage and anger among our compatriots.
With regards to the caste differences between the "Nepalis"and the Newahs, the post Gorkha unification age saw the Khas ruling class engaged in conforming the multi cultural populace into a Nepalese identity. This attempt to conform the racially diverse populace was confronted with a major problem. The conquered groups themselves had an internal system of caste differentiation like in the case of the Newahs. Therefore, for the construction of a Hinduistic Monarchist feudal society, it was essential to conform all aspects of human life i.e language, religion and culture. Giving the Newari ethnic group, which itself display internal diversity, a single identity and labelling Newar a lower caste in comparison to the conquering Khas, gave them eligibility to hold political and economic monopoly. Also, it perpetuated racial segregation and the consequent view of Newar as an "alien language" led to racial tensions --"NYAR".
