Have you ever questioned about 1000s of people killled during the partition riots (hindus were killed 3:1 muslims Ref: British records)? Have you ever questioned about attrocities done against Hindus in Bangladesh/Pakistan? Atleast have you ever asked a single muslim, why have they not question the dominant attrocities against minorities in muslim dominated regions? Open your eyes, if Prithiviraj chauhan had killed Ghazni in the first time, we would not have seen 16 further invasions. Learn from history.
