I tried to touch on the topic how a particular ethnic group is victimized in our history falsifying the facts. Newars have worked in every occupation like any other groups did in Nepal. But, the racist and ill-intended people have created several false rumours and funny phrases to undermine their contribution. There are records of intentional hiding of facts that our country benefited from the Newars. For example, it was Newari Lipi used to present in the UN as the script of Nepal; it was Nepal Sambat, kept alive by Newars, used to present in the UN as the calendar of Nepal; it was the music of Rajmati Kumati Song, the famous Newari Folk Song, used as the national anthem of Nepal for the first time in foreign land when Jung Bahadur had official visit in the Great Britain. These important information were attempted to hide in the history.

The statistics presented in OP reflects the large participation of Newars in Nepal Army, the icon of bravery in our society. But in general, the army profession is considered as a less promoted profession for a newar, and our society does not consider Newars fit for security jobs.

It is easy to make  a good talk with ideal wordings, but it is hard to erase arrogant feeling. Even if you don't care it now, you can not be fair if you need to decide who will be your bodyguard among the two boys - a newar and a gurung. It is likely that you may favor a gurung because you have once heard something against a newar in your childhood chitchat. Perhaps the above data could be eye-opener for those people who do not know about how much newar people are involved in security jobs. You can clearly sense arrogant and racist feeling among a few people who enjoy bashing a particular ethnic group despite saying that all human are equal.
