Discrimination is inevitable. This time it was about caste among Nepali in US. Tomorrow it is going to be about how many dollars we make-Minimum wages vs Career Job people. So, its just not us NEPALIS who discriminate.Remember, the motive of creating Caste system wasn't corrupted as it seems like;it was supposed to function so that all of us in a society would have a speific job to do. Alas, it didnt work but it sure did bring lot of differences. I, seriously recommend the victim to not to feel bad about those events. I am very sure that those people who turned you down are some glitches who need to be fixed. Also, there are tons of Nepalis who won't mind about your so called "caste". Having said dont come to conclusion that all BAHUNS AND CHETTRIS(OR any superior castes) will discriminate against you. About the thing about Chettris and Bahuns not talking well to Newars. I dont know about that. I have had quite a few Newar frens and we never felt that way. One this is for sure that whenever I went tho their house..they used to speak in Newari..which would bewilder me at times but again..I also learnt some "words";) Anyway, we all are Nepalis--Lets enjoy and live together
