What do muslims know of their glorious pre-islamic past in countries like India,Pakistan and Bangladesh? Absolutely nothing! . They hold their own ancestors ,the Indus Valley Civilisation,the authors of Vedas, Puranas,Upanishads,Yoga, Ayurveda,the Epics of Mahabharata and Ramayana, or classics of Kalidas,,the various philosophies (such as Advaita,Samkhya, Mimamsa,etc.),or even modern thinkers like Gandhi,Radhakrishnan,Aurobindo,Tagore,etc.,in utter contempt! They would rather uphold in great esteem tyrants,despots,madcaps,bigots and immoral muslims like Mahmud of Ghazni,Mohamed Ghori,Aurangzeb,Tughlak,and the like. These things are deeply ingrained in their minds generation after generation that they simply cannot see beyond their rotten idealogies.
