Davem, I think you are misunderstanding what
Lalwendë and I are saying. Neither of us is saying that individuals view fiction and reality from two different moral perspectives. Of course, peoples’ morals remain the same whether they are reading a novel or the newspaper.
But
Lalwendë's first post on this point (#470) was not discussing morality at all. Rather, it was simply pointing out that different individuals have different perspectives, beliefs and experiences and will therefore react differently to a text and take slightly different things from it. Surely there is nothing controversial in that. I think that the use of the word “individual truth” may have led to this confusion, but
Lalwendë has made it clear that, by this, she indeed meant “individual opinion”.
So, to start talking about the road that Saruman went down on top of that seems slightly odd to me.

But, since you and
HerenIstarian have raised the issue of morality in the context of what she said …
First, I should reiterate that I believe that there is such a thing as a moral consensus (or standard, if you prefer), or at least a consensus on what comprise basic moral values. (There are, to my mind grey, areas, such as the question of capital punishment which I raised earlier on this thread, but lets stick with the basics.) Although I believe that these basic moral values do not necessarily require a metaphysical explanation, that matters not for the purposes of what I say below.
Now, there are undeniably people who will read a piece of fiction such as
LotR from a moral standpoint which differs from the consensus (we discussed some of them earlier – the white supremacists). The point that I am trying to make is that, while their moral standpoint will be “right” to them as individuals, it will be “wrong” as far as the moral consensus is concerned. So, they will have to face the consequences (social, legal etc) if they seek to interact with others in society on the basis of their individual moral standpoint.
To use an extreme example, if someone was to read
LotR and decide that it justified unprovoked attacks on Arabic people simply because the human allies of Sauron came from the east of Middle-earth, that would be unacceptable from the point of view of the moral consensus.
But, although we can seek to persuade, we cannot (unless we bring in the thought police) force those whose moral outlook differs from the “standard” to conform to it. Now, if Tolkien was, through
LotR, seeking to persuade people towards the moral standard, all well and good. I salute him. But there will always be those (including amongst those who enjoy the book) who can, or will, not be persuaded.
