A core part of any story is the theme, the messages contained within. This isn't exclusive to anime, but is relevant to books, TV, movies, video games, etc.
I wonder about the kind of messages or themes present in some stories. The ones that are outright hostile to religion, especially Christianity, are certainly problematic. It's the rest of themyou have to be careful with. I'm not against any narrative that makes you think(should I be?), but it's important to think about if there is anything immoral within stories. I don't think conflict is necessary bad, it's a part of writing a story, and showing immorality is sometimes necessary in order to portray it as wrong. But here are just a few things I think about. I'm not trying to start a moral panic, and I'm not saying these things are definitely wrong. I don't know if they are, but I think it's worth questioning.
Fantasy magic, or other supernatural powers. Stories don't always eplain it or link it to witchcraft or other occult things.
Fantasy religions. Within fantasy worlds, there are sometimes fictional religions or fictional gods. Sometimes it's in the background as world-building, sometimes it's more involved.
Intelligent, non-human life. God created us, and we are more than animals. But some media makes other species that are also intelligent. They could be typical fantasy races, like dwarves or elves. They could be talking animals. They could be animals. Or they might be science fiction, like aliens. Or clones or robots, created by mere men.
Dragons. Sometimes fantasy portrays them as mere animals, other times as intelligent beings, but Christianity has never portrayed them in a good light that I'm aware of. Same question can apply to zombies, ghosts/spirits, or other fantasy monsters.
Dinosaurs and evolution. Some people think these are compatible with Christianity, some don't. But they are mentioned in some stories, so it's worth bringing up.
History. What do we make of anime set in historical periods, and their portrayals of Christianity and the Post too long. Click here to view the full text.
