Indian Bengali Hindu, You are talking to one, and owes all of his success to Indian education system and it's democracy. As far as Bengali Hindus are concerned, they have had stellar contribution to not just Indian society but also the defniation of Republic of India. With 5 Bharat Ratnas, to board members, chairman and MD's of most of the top private and Public sector organisations, pillars of art, literature, music, film, political activism, science, mathematics, military and space) Bengali contribution to Indian society and India's contribution towards empowerment of Indian Bengalis has been of perfect osmosis. So your idea of Indian Bengali doesn't even scratch the surface of nationalistic aspiration for an Indian Bengali.
