And completely oblivious of their legacy, with nothing to show for their descent, other than their location. When the British take pride in Stonehenge, they do so not as descendants, but as representatives of humanity who are living in the same place as a monumental achievement of that same race many millennia ago. When the Romans of today, or the Italians, or French or Spaniards or Portuguese - indeed, Europeans of any former part of the Roman Empire - glory in the achievements and the heritage of that Empire, they have their language, their law and the living transformation of art and architecture from Roman times, their literature, heavily influenced by Roman literature, and their history, which flows in direct line from the history of the Romans. When the Greeks take pride in the matchless legacy of Hellenistic civilisation, they have similar, direct links to flaunt.
So, too, inhabitants of cultural India, including inhabitants of present-day political India, of Bangladesh, of Nepal, of Bhutan, of Sri Lanka certainly, of Burma partially, have the right to speak with the pride of ownership about the many waves of cultural rejuvenation that the sub-continent was fortunate to enjoy. Those who wish to celebrate their common roots, Afghans included, have a right to do so which cannot be attenuated by cultural fascists of either the Hindu or the Muslim variety.
Those who wish to claim this rich heritage are free to do it. Those who do not wish to do so are equally free not to do so, and may stay outside, isolated and belonging nowhere, picking at the unhealed scabs of their self-inflicted injuries, and quarreling among themselves over the details of their detachment while the rest of the world passes by.
