Oh, khaate Bimal Thapa USA, go to hell, okay?  Obviously you want to divide the Nepalese society that's already in such a dismal state. One of the reasons why Kids back home are so much into violence and drug addiction is this, that their parents and society puts hatred in their heart since early childhood. They don't have no sense of a nation, or a society, no wonder every one in our government is so corrupt.

Samsara bro,

There are several stories and so called holy books that is discriminatory to other castes. Like this code of Manu in Manusmriti, which was written by a king about 2,000 years ago. YES, Manu was a king, pressumably, the first human king. But of course bahuns were the unofficial law makers. It was all a propoganda of a few elites with power and education in their hands. It was a legal authorization of slavery towards the Shudras (peasants), by priests and landlords with the help of religion. But If you look back 2000 years ago, which society didn't have slaves?

In those times, all races and tribes were in conflicts when they contacted each other and whoever won, enslaved the others. In many cases the winner race even exterminated the entire population of the defeated race. They were all animalistic and barbarians hence such ruthlessness towards the others. People even today act agressive and defensive when coming in contact towards other races and you are talking about millinea ago.
