In Mumbai, some folks eat a lot of pan, they sell a lot of pan, they spit a lot of pan, they do not have good manners, the taxi and rickshaw drivers try to fleece you when you hire them form the airport, some people stink when they stand next to you in the train, they do not speak Hindi in the Mumbaiya style and finally if they go on a holiday they return after 6 months. Now this is not good enough reason for bashing anyone.
Just imagine if the bhaiya did not eat pan and was decent sort of a guy who smiled and helped all, could Raj have whipped up the emotions of his stupid party men and women?
Same thing about Muslims, it is there aggressive wearing of the religion on the sleeve which makes them unpopular.
Have I provoked you?
