As said, this question refers to Hindu�s and it refers to Pakistan, so it would make sense to respond to the specific points rather than go off in tangents as is so often the case.
During 1970 and 1971, huge massacres were perpetrated upon Hindus, by the Pakistani army. A proper study into the casualty figures has never been conducted. Estimates for the number dead are up to 3 million. Millions of Hindu women were raped and kidnapped in this period. It was one of the largest massacres in recent history, and also one of the most ignored.
In 1977, General Zia ul-Haq led a military coup in Pakistan. He introduced Islamic Law, which further excluded and marginalised Hindus.
In 1989 and 1992 over 300 Hindu temples were destroyed. Many Hindus lost their homes. The largest outward migration of Hindus from Pakistan since Partition took place during these years.
Since before the end of colonial rule in 1947, the land that was to become Pakistan had a large proportion of Hindus, accounting for over 26% of the population � now via, mass migration and/or genocide that figure is around 2%.
