Let's see some of the gems from that credible, sectarian website you have uncritically endorsed...
The Indian historian Professor K.S. Lal estimates that the Hindu population in India decreased by 80 million between 1000 AD and 1525 AD, an extermination unparalleled in World history.
1. The population of India was c67 million in 1000AD, so unless there were around -13million Hindus in 1525...
2. As noted in a peer-reviewed scientific paper I previously provided, genetic evidence shows millions of Hindus converted to Islam, hence you would expect an additional decline in the Hindu population.
“There is no official estimate of the total death toll of Hindus at the hands of Islam. A first glance at important testimonies by Muslim chroniclers suggests that, over 13 centuries and a territory as vast as the Subcontinent, Muslim Holy Warriors easily killed more Hindus than the 6 million of the Holocaust. Ferishtha lists several occasions when the Bahmani sultans in central India (1347-1528) killed a hundred thousand Hindus, which they set as a minimum goal whenever they felt like punishing the Hindus; and they were only a third-rank provincial dynasty.
Remember how wrong the last "Muslim chronicler" you quoted was? Yet now we should assume that these are, in fact, accurate?
