The atrocities on Kashmiri Pandits were real. The fact was that during the British rule most apple orchards were owned by the few rich Kashmiri Pandits who had homes in the UK and most were related to royalty. The laborers were the rest of the Kashmiri Pandits who were poor and the majority poor Muslims. When we defeated Pak in 1971 they started this propaganda of Hindu vs Muslim and it worked well cause the poor lived a very poor life in Kashmir, the rich enjoyed luxury, when the killing first started, the rich pandits moved and the poor got massacred. It's not just Pandits many Sikhs used to live in Kashmir too.
Having said that, the movie Kashmiri Files is making news for all the wrong reasons. Agnihotri is a BJP stooge who is villanizing one entire community whereas terrorism knows no religion. If you want to watch a beautiful, sensitive movie on the Kashmiri Pandits, watch Shikara instead, a Vidhu Vinod Chopra-directed movie which released in 2020.
