As I had mentioned in my other comment, our grandparent generation holds on to some aspect and that it is stronger in villages. But having travelled through India extensively, the kind that goes on in Bengal is no comparison to say Rajasthan, Uttar Pradesh, Karnataka. That's the reason you will politicians have caste centric campaigns and manifestos. In Bengal, politicians know that caste will not get them votes, BJP is trying its level best to split the vote along caste lines.
