Muslims were responsible for one of the largest mass murders in history in India and they wonder why they are not loved?

‘How can they hate us so much?’ asks father of Muslim teen brutally killed in attack on train in India

The slaying of a 16-year-old was the latest in a string of anti-Muslim attacks in India during the Islamic holy period of Ramadan. Tensions have risen since the Hindu nationalist government restricted the sale of cattle for slaughter.

Some 400 million Hindus were alleged to have been killed during the attempted Muslim conquest of India.

...
From the time of the Umayyad Dynasty (711AD) to the last Mughal, Bahadur Shah Zafar (1858), so widely praised as great leaders by Indian historians themselves, entire cities were burnt down and the populations massacred, with hundreds of thousands killed in every campaign, and similar numbers deported as slaves. Every new invader made (often literally) his hills of Hindus skulls. Thus, the conquest of Afghanistan in the year 1000 was followed by the annihilation of the Hindu population; the region is still called the Hindu Kush, i.e. “Hindu slaughter.”

The father of this teen may not know the history of what Muslims did, but the descendants of their victims have not forgotten.

Others put the death toll lower but it is still a significant number of around 80 million killed.  In Africa, 110 million blacks were killed by the Muslim conquest.  Over a million Europeans were enslaved by the Barbary pirates where most of them were chained to the oars of one of the ships where they remained until they died.  Others were castrated and used as Eunuchs.  The death and destruction imposed by Islam were greater than the Nazi and Communist genocides of the 20th century.

Besides the current terror threats, it is hard to tell those with a sense of history that Islam is "peace."
