"Postmodernism has made it fashionable to deconstruct what its adherents called the 'grand narratives' of history, seeing these as little more than the stories of the triumph of Western progress which was largely achieved by suppressing or violently overthrowing other groups. More problematically, postmodernists advocate that all identities be dismantled or blurred and view all positively distinctive cultures as being oppressive to weaker or less assertive ones. This idea might at first seem reasonable, especially when viewed through a postcolonial or subaltern lens, but it opens the door to a pervasive cynicism and narrowness of vision with no workable criteria of value in aesthetics, politics or philosophy. The postmodern insistence on denying such identities as Indian and Western leaves non-Western cultures vulnerable to even further exploitation because they are denied the security of possessing a difference which is real and defensible. Postmodernism, then, tends to undermine the particular reality of the non-Western culture that might be in need of being affirmed, protected and developed."
