Yes, look beyond jaat bhasha etc. But we have to know the true history of Nepal and Newar. It doesn't mean that Bahun Chhetri do not belong to us. They also have thier own history. If the culture, tradition and language of Newar have significant value, let's admire it. To teach Newari language to Newar children is the must. Even we are teaching only English ( Hipocrates). It has been scientifically proved that any one who knows more than 3 languages are definitely more intelligent than who does not. It is also wrong phenomenon that Newari speaker were/are/will be weak in Nepali. I know a native Newari speaker who scores the highest mark in SLC AND ISc.
