Good job Crazy horse what we need is knowledge of our history and unity. Also you know we are ALL ONE we dont need to blame or pinpoint someone. I know everybody realizes this but for some it takes time. I am pretty sure if we have an earthquake in Kathmandu or in big cities of Nepal I do not think Newars will only pick Newars or Bahuns will pick only Bahuns. We need to realise the importance of life given to us by GOD and enjoy among each others.
I understand there are different caste system we can  also utilize is for the benefit for example: Nepal is closing(bandha) almost once a month. So Newars or Bahuns or Chettris, or Tamangs any leader from these castes can come up and say we Newars are not participating in the rally or breaking the down the building or the cab....
So there are lots of things we can do folks.
