Tropes wouldn't exist if they did not illicit a reaction within people. People are comparing the relatability of stories with their own mental view of the world which may not be true.
Blacks compare stories of slavery to their own circumstances while no black has been a slave in America for years.
Millennials compare everyone they consider to be evil to death eaters or Voldemort even though magic does not exist.
People compare video games, movies, and music to actual violence and teaching violence even though in media the reactions to violence is exaggerated. There's only a few people who's kill count was beyond 100. There's only a few people that have survived traumatic life threatening injuries once while media shows people to be fine after a gunshot.
At some point in your life you were told to read books at all cost as a kid but you did not understand why. Books have become this untouchable art form and some want it that way to influence your minds. People don't understand that these things are entertainment first, our real lives are usually boring. The excitement of books and media is relatable to us because it is not us and any near comparison illicits a excitable reaction from us. But where I can detach myself from video games and the extreme circumstances in those games book readers have yet to learn this because they were never told to the contrary.
