now you are talking mr. kailo I completely agree with you and the weapons of the Ranas and Shahas were to divide the Nepalese based on our ethinicity. Just one point bahun, jyapu, bhote and madhise.  Do we ever talk about chettris hell no. We dont need to read history books to understand this. We have this experience from every corner of Nepal and we just need a smart brain to analyze this and unfortunately not all have smart brains thus they scold bahun, bhote, jyapu and so on .And chettris are never blamed......
