Ben Shapiro mentions this in his book primetime propaganda. How powerful Hollywood producers are engineering what society thinks through the media usually to the left of politics. They create a character that everyone comes to love and then create a storyline where they do something controversial. This way they get people to accept controversial issues they would usually be against (make something that is usually seen as wrong/immoral seem OK and acceptable).
One example given is from the 70's
sitcom Maude. During the '70s abortion was a hotly debated topic and many were against it. A year before the Roe v Wade court case the main character Maude has an abortion in one of the episodes. As Maude was a character that everyone loved this helped changed attitudes towards abortion at the time and paved the way for legalizing abortion.
Hollywood takes lovable characters and gets them to do controversial things and this makes it acceptable for people who love the shows and the characters to accept things they would not usually accept because they think if it is OK for the character they like then it mustn't be too bad. This has been going on for years but many people don't realize it. It has shaped the way society thinks.
Not only is Hollywood influencing the way we think but they give themselves awards for doing it. We see this in the way actors get on their soapboxes virtue signaling about how we should be saving the planet and why certain minorities have not received more awards. Accept the public has caught onto to their hypocrisy and are rejecting the awards in droves.
