Of course....I am not sure about BD people, but people in Paschimbanga are very much cultural and they really stick to the roots and language wherever they go...That is why Bengali language and Bengali culture is considered to be a one of the most classic and traditional culture in India and even in Bollywood...Sticking to their language and root is a thing that should be learned from Bengali people......
West Bengal is culturally very strong. If the whole Bengal were together I would prefer west Bengal as capital of culture.
