Unlucky-for-Some wrote:well not much sexism, certainly... but the racism thing is interesting. If every member of a race is demonstrably evil, is it in fact a racist slur to attribute evil to members of that race?
Yes, this is pretty much the definition of racism. They have Detect Evil spells that "prove" someone deserved to be killed without a trial (especially given that nobody but divine mages understands how these spells work, so a person can claim to be a paladin, squint funny at the mark, and claim to have detected evil, and none of the surrounding peasants will have a Spellcraft check capable of detecting the farce). We have books like "The Bell Curve" and flawed pseudo-science studies, paid for by "think tanks" and "charitable organizations" with an interest in proving a certain social class "undesireable". There's not really much of a difference. (Maybe a *little* bit of one, when you get into things like actual Demons and Devils whose existence might be empowered by the mere thinking of bad thoughts; as far as we can tell, such do not exist in our world, but again the average D&D peasant has only a cleric's word that they exist in his either.)
While certainly there are examples of elves and dwarves holding questionable opinions about each other that might be expressed in racist terms, orcs pretty much genuinely seem to deserve every epithet they are given by the other races.
Actually very few non-Tolkien portrayals of Orcs cleave to the stereotype he established for them (Warhammer Fantasy is the only other one I can think of). In most modern works, Orcs are just another sentient species which humans discriminate against, simply because they're ugly and live in the wilderness. Often times they're driven into accepting the patronage of demons or Evil gods because nobody else will have them, but they start out as just "people" of a slightly different sort; few authors besides Tolkien (and, in imitation of him, Gygax et al) have tried to claim that evil is "in their blood" and inevitable. The presence of half-orc characters instantly suggests that this "taint" is mostly the product of ignorant supposition and prejudice.
A better example of the same principle you're getting at might be the chromatic dragons. There's fairly strong evidence to suggest that these are just naturally vicious alpha-predators with inherent destructive and covetous urges. But then, human beings have some of the same urges too; at most, the orc and the dragon and evn the demon are just exagerrations of the same tendencies. If human beings can be redeemed, maybe every other species of creature could be too. Certainly, methods such as the "Sanctify the Wicked" spell in Book of Exalted Deeds exist when can transform Evil creatures into Good ones, and they work on anything other than an Outsider (such as a demon). So no, orcs need not be evil, neither need even dragons. And there is at least one published NPC which is a Demon (specifically a Succubus) who not only became Good, but took Paladin levels! So someone at Wizards of the Coast decided at one point that it was possible for even the literal embodiment of Chaotic Evil to become Lawful Good, just by deciding to.
So is it racist if it's true?
That depends on whether truth can ever be objectively verified. Which is probably even harder in a world of epic-level Rakshasha illusionists and gods of deception than in the real world (though not by much, given the implications of quantum physics and the Heisenberg uncertainty principle). Ultimately, the burden of proof is on the one who wishes to commit what is objectively an atrocity.
