just because he added Hindi with urdu doesnt mean that he is Indian. Our National Anthem is in persian (farsi), does that mean we are not true Pakistanis??? grow up yall. India and Pakistan would be the biggest powers of the world if they unite together but no! we have ppl who hate someone who sang in Hindi. If you look back in the history, maybe u can see how Pakistan and India was divided. First East Pakistan and then they left Kashmir so that we can keep fighting among ourselves. We had 72 war because of East Pakistan and then look at now, what are we doing? still fighting with india and vise versa. They divided the two nations so that we could never get along and become a powerful nation on earth.
Regarding his culture and religion, i dont care what he does, its his life, he'll pay it in the end. Who the hell are u to impose your values on him?
