Confused Soul i agree with you in many things.
 Nepal has been manipulated by corrupt politicians, shahs and rana regime.
The elite ruling class of Nepal have never thought of Nepal except for their own benefits of their party
and their own kind(nepotism).
It's not only Newar that have lost newari scripts and bhasa. Even other janajatis have lost their many
culture and bhasa. It is mainly because due to Sanskritization which the high caste ruling class was trying to make Nepal into Asali Hindustan.
They had very narrow mind in how to bring Nepal forward. By instilling Indian priest at the Pashupathinath temple, varna(class) system in Nepal became worsen.

I learnt from one of the text that the fire at one of the office in Singha Durbar was intentional where variety of treaties and important scripts were collected and kept for safe keepings, later only to be consumed
by the fire. All this has to be accounted for and keep any individual responsible for.

But rest be assured that People's Party have begun and will continue to fight for the people.
