Well said Baba Bengali. It is indeed true that ALL people in the entire Indian Sub Continent extending from Afghanistan,Pakistan to Combodia and Indonesia were Hindus since time immemorial. Most muslims in this region are converts - forcibly in most cases. Islamic rulers who invaded a fragmented India, raped, plundered and forcibly converted thousands. Chandini Chowk in Delhi was one place that witnessed the conversions during Moghul era. There are several sources but if you can think, you will figure this truth.
Also, don't rely on the Aryan theory. Indian civilization is the oldest in the world, and people migrated out of India. Not the other way. Max Mueller who promulgated the Aryan theory confessed and stated that that was incorrect. Many modern Historians and anthropologists have written books and widely acclaimed papers that shoot down the Aryan theory.
Some folks on this forum seem to think that peace can exist between India and Pakistan. I don't think so. Its a clash of the cultures. Hindus are not known historically to go looting, raping and killing. Hopefully Pakis will be sensible and not make Hindus start now.
