@Surendra Shakya I think that it is not so much about ignorance but it is about trusting the other group. And, it is not only our history, it is the history of the world. Otherwise, a small English regiment wouldn't have been able to rule the Indian subcontinent. The modern urbanization has finally brought the different ethnic people together in Nepal. And, only 18% of Nepali population lives in the cities. So, the majority of Nepalese still live in the mono-ethnic society. They are finally learning to trust each other and working for the greater good. I actually think that we are very intelligent people. You can look at the Nepali Ukkhans. They are full of wisdoms. It is only matter of time that we start to trust each other and leave a mark i this world with our collective wisdom.
