There is no use crying over Bihar state of affairs. It is not going to improve. What I would suggest is lying and hiding your Bihari identity to the hilt. Then only you can be accepted in a civilized society.
I am a popular media personality in USA and never tell anyone that I am a Bihari. If I do I will lose all goodwill. Even though my surname clearly suggests I am a Bihari, most people hardly know it. And if you can westernise your accent, it helps immensely. Thus you can get around the ignominy of being a Bihari pretty easily.
