There are gujrathis, marwaris, tamilians, mallus, kannadiagana etc etc in the city, but none of these use their festivals to show their strength. Ask a mumbaikar how most of these north indians live 10-15 in a small room, living filthy , driving auto/taxi illegally, putting up bhel puri, paani poori stalls illegally. Any person who goes a particular place should respect the law of the land and respect local cultures.
Here are few question Why do you always see biharis in Indian railways ? Why are the Recruitment Ads for Mumbai, Maharashtra region is put in newspapers in UP, Bihar? Doesn't Lalu , Paswan favour the people from his region, So whats wrong in Raj Thakrey raising issues about Maharastrians and Mumbaikars ?
A true mumbaikar even those from UP, Bihar who are settled in mumbai for long time and tell you how a big mess mumbai has become, slums , crimes , etc etc. And we all know who is responsible for all this. The party which claims that they have made uttar pradesh as UTTAM Pardesh are now out of power in their home state come up with a new slogan UP HAAMRI hain ab MAHARASTRA ki baari hain. Let these parties first take care of UP and then think about other states.
