Jaya bachchan is non sense. Try to understand. This is happening in Mumbai toady but will happen all over India in next 10/20 years. You MUST respect local language and culture. Kannadiga beat up Biharis last month. Biharis were killed in Assam couple months back. Shila Dixit, Delhi CM last month said the pathetic condition of Delhi is because of people from UP and Bihar.
All of these were NOT maharashtrians who had objections to people from UP and Bihar. If you are not ready to respect local culture and language then you WILL NOT be welcome anywhere.
As far Raj Thackerays contibution to Maharashtra, I think Jaya Bachchan needs to read some books. She should know that it is Raj Thackeray who started Shiv Udyof Sena who provided employment to lakhs of people!
