Query: Why does the distinction between fiction/nonfiction matter?

If you like this book, you should do so regardless of whether it is really fiction or nonfiction. (Is there really much of a difference between the two?) If a book doesn't hold up when you pretend it's fiction, why bother reading it? I mean, what matters here is that to read a book is to experience the author's words. The question that people need to be asking is not whether there is some factual evidence behind them, but whether they move you from one to the next. Does she write good sentences? Good paragraphs? Is there beauty in them? Is there tragedy in them?
