Whatever happend between MNS and SP is purely political issue and the common public is being targeted. SP like MNS is a regional party which has boundry limit of UP.It could not win even one seat in Bihar assembly.MNS has the same territorial limitations. Thousands of UP and Biharis migrate to greener pastures like mumbai because of social inequality,negative progress,lawlessness.corruption,police and political atrocities. If you look at these migrant,they are mostly from the lower strata of economical hirearchy. Now,what MNS is objecting to is the SP leadership comming here in Mumbai and trying to creat a citadel of power by useing these migrant.This will never go well with any local political party and also with the local population.This clash is unavoidable. There is no need for the rest of the Indians to take a stand as if something big has happend because we Indians are known for this kind of regionalism.Has it not happend in other states ever before?So don't become saints because all of us are opportunists.We change sides when it suits us. What is happening in Hariyana and Punjab,Karnataka and Tamilnadu in Bangaluru,Assami and Bengali?
