“Why is the onus only on Hindus to accept Muslims and not the other way around?”
Hindus, to put it bluntly, feel victimised in a Hindu-majority country. Some even want to turn India into a "Hindu Rashtra." In turn, some demonise Muslims, most of whom are descendants of victims of the conquerors and forced converts. But history cannot be undone or set right by revenge narratives. Then what is the way out? How can Hindus and Muslims live in peace?
We need an Indian, perhaps subcontinental, truth and reconciliation process. Muslims would acknowledge and disassociate themselves from the bloody and horrific history of the conquest of India. Hindus, in turn, would let go of their hurt and pain that can turn into retaliatory rage.
