I agree. When people claim that fiction affects reality, they don’t mean that works of fiction or the characters depicted in them are real, they’re talking about how fictional works can encourage harmful attitudes and behaviors. For example, K. M. Claude has drawn fetish artwork of children. By posting this kind of material publicly, they create an environment where it’s normal to view children as sex objects, which attracts pedophiles.
“I swear Claude and their crew think the phrase ‘Fiction can affect reality’ means that it is reality and that isn’t true. They just don’t wanna own up to their own bullshit.”
