I believe this topic is the origin of ignorance and illetracy.Those people who dont know about the term Neapli will argue for it.They dont know that Nepali does not only mean Bhramin or Chettri. There r lot of other castes.More over due to this concept our country is not developing.If you will treat your fellowmen as ur enemy you will get the same thing in reciprocal.There r lot of bhramins Chettris,newars including marwardis or others who r involved in bribes and doing lot of wrong things and lagging the country to hell. The most worst of all are the politicians. How many marwadis are in politics. So it depends upon the individual not the caste. And I will suggest to make ur concept broad otherwise Our country will never able to do better due to this stinks concept.
