Who are North Indians? Do they include Punjabis, Haryanavis, Rajasthanis including marwaris, Gujratis, Sindhis,Madhya Pradeshis Delhi walas,and Kashmiris? Every community has its own customs, food habits, living style and they celebrate their religious festival in their own style. They feel more comfortable in living the way they have been living through many generations. There is nothing wrong in letting them live the way they want to live so long as they do not step on the toes of the local people.The best example is the USA. People will change in time on their own. Raj Thakeray is only trying to gain political mileage and that Marathi Manoos should understand.
