Lets not say UP, Bihari, Gujrati, Punjabi, Marathi, etc....Say Indian first. It bring such shame to me to see you educated (civilized) people can write such a rubbish. So whats the difference between you and those politicians who wants to bring unstability to our soceity.
Think more from outside, why are they trying to do this. What they want to achvie with this. NOTHING!!!!!!!!
Also all those people arguing for migrants to mumbai, specially UP and Biharis are bad, see if you have friends from UP or Bihar decendent. Just think. Jai Hind.
