Though you tried hard to show how much you r living in a racial harmony, you showed some attitude here.

'whenever he gets calls from Nepal or his relatives around here he talks in Newari that I don't understand' (Analogy: your foreign friends wondering why you do the same (talking in nepali) whenever you get call from your nepali friends or relatives from Nepal (please don't make an excuse by saying because they can't speak in english).

Why can't you appreciate other's cultures and language? What is your problem of him speaking in newari?

'he is a Votey' (Do I need to write an analogy here too?)

Besides these two issues, I can't agree more with your opinions.
