Rai, I agree with you. I am from the so called "high caste" but I have seen discrimination against the so called "low caste". Let me share one of my experiences. It was few years back, Me and my friend had to go to one remote village in far western Nepal. We were there to design one construction facility. The VDC chairmain invited me to dinner but refused to have dinner with my engineer friend just because he was from the "low caste". i was so angry that we left the place immediately.
