This might be a hot take for an anime enjoyer, but what immunity are they talking about here? Immunity against nudity? Fanservice?
I’m leaning more towards “people losing immunity towards nudity (in shows)” but that’s one extreme. If every show on Earth has people fully-clothed, covered from hair to toe, and porn is relegated to an extreme taboo that one would go to great lengths and at great risk to access (kinda like Shimoneta, I guess?) then maybe? But even then, sex is such a human need that people will find ways.
Now, this might be a wild shot in the dark, but if they’re talking about lack of fanservice leading to people not having sex, uh… Japan has a lot of problems with young people not having enough children, but I don’t think lack of fanservice has anything to do with it, and more about the pressures and bleak prospects.
IDK, I just don’t get it and maybe someone who has access to the original interview quoted here can clarify things?
