Those who are saying that "it's just a movie or TV show, no one takes it seriously" doesn't know shit about propaganda. Hitler appointed Joseph Goebbels as his propoganda minister. Films were used to create a facade, an allusion of reality carefully created and manipulated

-to allure the audience and coax them with false ideas. This is happening with our TV and films right now. Little bit of hinduphobia sprinkled over some relevant plot. Repeatedly portraying Hindus as terrorists, mass murderers or misrepresenting hindu culture is becoming norm.

In films or TV shows based on reality, they often manipulate facts and history to show Hindus in bad light. Or just outright, without any subliminal propoganda they just show it directly e.g Leila by Netflix
Currently Anushka Sharma's Patal Lok is full of propaganda

And this will continue. To counter this giant propaganda machine is no easy task, but one can read and research on things and not just believe in everything they see on TV and movies. This will atleast slow down the spread.
