Being Indian I will forgive you for being retarded
But seriously look it up. All scholarship says that when Mohammed bin Qasim came up Indus River, all the people were hindu.
So what happened to the Buddhists? Simple, the same thing that happened to them in the rest of India. Convert to hinduism or die.
Hindus like to make up fairy tales of forced conversion to Islam. But India is 80% hindu today. That's not forced conversion.
Buddhism on the other hand..... Almost 0% left... Hindus know how to fully convert.... They are even trying it now on minorities.
