there is a systematic racism in nepal. it is embedded within a soceity. it was and is a part of our culture (i am not approving it, just telling you what i think). kaha bata aayo bhanne kura chahi jaba bahuns migrated from modern day india, and settled around modern-day nepal, they classified themselves as the highest caste and classifed others as loweer caste so that they can become the most powerful and respected class in society. simple as that. no rocket science needed.
