Ok point 1. Eddings's books are not racist. Saying so is just silly. If for no other reason than if you look at how the thinking that each race is this or that is portrayed... it is in fact showing a flaw in even these old and wise characters. Eddings writes flawed characters and flawed hero's. He has given these all but immortal and powerful beings a very human and short sighted view of the world that they are out to save. It is in fact brilliant writing. This does not mean that the books contain racism though. In the end more of those preconceived ideas are shown to either be false or pressed upon the people but the hands of outside forces (their Gods) or... In the end one is made to see them as more than just the label they had been given.
Point 2. (Yes Fantasy is a reflection of reality and the ideas in reality so yeah when creating a "bad" race there are going to be elements of "racism" in there because unfortunately that it just never far from 60% of the worlds thinking. This is a shame but well most people do little about it and it is all very well to point a finger at fiction and media and say "they have to stop first" that it just not how the world works. Media is always and forever a reflection of what is in the world and what is most prevalent in the immediate world/country wide culture/way of thinking about a topic. This has always been so and yes there have been a few times when the media (after a decision has either been made by the authorities (laws have changed and so on) or by a push by a group/s of people trying to change the currant culture) has been used to help push a new culture/way of thinking out into the world but always after the idea has taken root in a fair portion of the people of that country. Media is a tool, a reflection, a way to talk about those currant topics that are already widely or growing in the universal consciousness.
Point 3. If we are to go on this idea that any author that sets any broad defining cultural features for a race in their work using racism, then all fantasy and sci-fi is racist. I have yet to read a book that does not in some way define a race as mostly being Kind, mean, stingy, drunk, augmentative... Pick your poison! It is a trope, a easy way to define and separate one culture from another beyond just looks and language or dress. It has been used since people first started to tell stories around the fire and I don't think that there is anything inherently wrong in doing it. I don't think that is promotes racism or says that it is ok.
So the argument it just moot however you slice the cake. Fiction is always going to deal with racism, from one side of the racism outlook or the other, in someway as it is a relevant issue and one that always brings forth a emotional reaction.
Whether Eddings has promoted it, or given the appearance of promoting it, is irrelevant to my answer to your statement on the order on tackling racism - real world/popular media. Also, the idea that you appear to be stating, that just because something happens in real life its use in fantasy should not be questioned. I apologise if that is not what you meant to say but I have no idea what idea you were trying to convey if that was not the case.
I answered these things independent of Eddings, because whatever Eddings has done or not done is irrelevant to my disagreement with what you said.
My point is that I don't see why talking about currant issues in some form or another in fiction/media ought to be a problem. It needs to be talked about somewhere and where better than in a totally and utterly fictional world? It is like the perfect neutral place to talk about this stuff as it free us from the emotion of the past and allows us to see the feelings, ideas, and emotional reactions that may be behind some behavior more clearly than if viewed in the real world, with real world history. We will never solve the issue or racism or any other kind of intolerance that we face in todays world if we do not understand where the issues are coming from and what powers them.
One just can't fight a fire without knowing what will best put it out. To learn how to best put out the intolerance issue we need to talk about it and fiction is one of the best ways to go about that. To show in a "real" way what racism is from both sides of the fence, because there is a there side to the racism fence just like there is to everything. It does not mean that a book that may or may not contain racism is in fact promoting racism or should be looked down upon for having something that may LOOK like racism.
Yes we should always question what we read but we should never stop authors from raising currant topics, theological ideas, philosophical ideas and ideals for us to question.
