You people claim to be most educated and are staying in one of the most developed countries of the world. But when it comes to your mentality, its worst of all. What will other do who are still in traditional world and it’s your duty to bring change in their thinking. Racism is one of the very deadly hidden hurdles for country development. I am a bahun . What you call for puru bahun- o ya- upadhaya bahun; but I don't feel anything being that bahun. I am a nepali and that’s all. My wife is newar (pure newar of kathmandu). We have got married and brought changed at least without family and relatives. Show people how two race people can get together. Believe me this will be one of the most unseen (yet very productive) contribution to your family, community and your country. People feel fully energized to put others down, but just recall when you have appreciated someone who is not from your type.
