This is rubbish. Nobody can do that. Even in Aaurangzeb's time Hindus survived. Look at Hitler. He could n't kill Jews. Look back in history; has any Hindu king or ruler has acted the way you have mentioned? Even Pakistan has some Hindu temples and minuscule Hindu community left. So nothing will happen under Modi's Raj. He has to face today's world. It is not so tolerant of such behavier.
