Thousand of hindus have been butchered, women folk abducted, millions converted to islam, thousands of temples razed to the ground, converted to mosques or mausoleums, what is the position of hinduism now? It has not vanished. Buddhism had spread to south india as well along with jainism. Jainism now survives, but not buddhism, why? You must read sri lankan history.
Romila Thaper's version of indian history will soon be forgotten with more non-left historians relooking into the wild guesses made by the western historians and indologists and their thaper-like disciples.
