This is what the Great Will Durant had to say about the Islamic conquest of India.
"...the Islamic conquest of India is probably the bloodiest story in history. It is a discouraging tale, for its evident moral is that civilization is a precious good, whose delicate complex order and freedom can at any moment be overthrown by barbarians invading from without and multiplying from within." Almost all the Muslims of South Asia are descendants of weaker elements of the population who had succumbed to forcible Islamic conversion." )
"The Mohammedan conquest of India is probably the bloodiest story in history". The Islamic historians and scholars have recorded with great glee and pride of the slaughters of Hindus, forced conversions, abduction of Hindu women and children to slave markets and the destruction of temples carried out by the warriors of Islam during 800 AD to 1700 AD. Millions of Hindus were converted to Islam by sword during this period. "
"The growth of Buddhism and monasticism in the first year of our common era sapped the manhood of India, and conspired with political division to leave India open to easy conquest. When the Arabs came, pledged to spread a simple and stoic monotheism, they looked with scorn upon the lazy, venal, miracle-mongering Buddhist monks, they smashed the monasteries, killed thousands of monks, and made monasticism unpopular with the cautious. The survivors were re-absorbed into the Hinduism that had begotten them; and eased the return of the prodigal by proclaiming Buddha a god."
"At Elephanta the Portuguese certified their piety by smashing statuary and bas-reliefs in unrestrained barbarity; and almost everywhere in the north the Moslems brought to the ground those triumphs of Indian architecture, of the fifth and sixth centuries, which tradition ranks as far superior to the later works that arouse our wonder and admiration today. The Moslems decapitated statues, and tore them limb from limb; they appropriated for their mosques, and in great measure imitated, the graceful pillars of the Jain temples; time and fanaticism joined in the destruction, for the Hindus abandoned and neglected temples that had been profaned by the touch of alien hands. "Even in its ruins the Temple of Shiva at Elephanta, with its massive fluted columns, its mushroom capitals, its unsurpassed reliefs, and its powerful statuary, suggests to us an age of national vigor and artistic skill of which hardly the memory lives today."
