If you think that Nepalis are the ONLY ones who discriminate then you are wrong, dead wrong. I have many Indian friends from different parts of India and they make fun of others or I should say discriminate. There are lots of racial tension hidden in American communities if you cannot see that either you live in a very big metropolitan area, do not work or work from home or lack understanding of the societies around you. Try to volunteer in public places like the library or local hospitals you will get a feel for the racial tension that lies in your society. Sure they will smile and be civilized with you that does not mean there is no racial tension. Sometimes you have to scratch the surface and look deeper to see whats inside.
