Now that's a rabbit hole of a theory. Just like with anything, a "stable" person can live in a world with this kind of make believe and enjoy the story telling devices being used. However, someone less "stable" that can be less able to make these distinctions. Does that mean we all can't have it because of a small number of people? If that's the case, then I would apply this same rule to any and all social media. Clearly, some people can't handle it, so nobody can use it.
