Ray Bradbury saw it all coming

"They passed a law. Oh, it started very small. In 1950 and '60 it was a grain of sand. They began by controlling books of cartoons and then detective books and, of course, films, one way or another, one group or another, political bias, religious prejudice, union pressures; there was always a minority afraid of something, and a great majority afraid of the dark, afraid of the future, afraid of the past, afraid of the present, afraid of themselves and shadows of themselves.”

The Martian Chronicles, 1950.
