The reality is that medieval types did not think of race the way we do and did not pay much attention to it. Nationality and religion was far more important.
Errr.. much of the reason that a medieval person would not think of race in the way we do is that its virtually impossible to separate the concepts of race, nationality, and religion in a medieval text. The medievals or ancients wouldn't have spoken of a race, but of a nation with the assumption that the members of that nation were of a single common ethnic origin. Similarly, they could understand religious conversion to be an individual and national event in a way that we simply don't.
For all practical purposes, this is still playing out in Europe, as it seems every different historic ethnic group wants to carve out its own sovereign nation.
Skin color in medieval Europe plays a small role in defining nationality and ethnicity in no small part because the average medieval would have encountered such a small range of skin tones. A 'swarthy' skinned person could have meant almost anything including north africans that we today would tend to lump together with 'white'. St. Maurice has a black face for much the same reason that he's wearing high medieval armor - the artist has very little conception of what St. Maurice might have looked like. As evidence, witness the various items passed off as relics of or associated with St. Maurice that are obviously of medieval origin - and not even what we'd call 'forgeries' since they make no attempt to look like 3rd century weapons. St. Maurice has a black face solely because he's associated with Africa. It's not meant to protray his actual skin tone, even if the artist had some idea what a 3rd century Egyptian woudl have looked like, but to simply convey 'African' to the viewer of the icon.
The real St. Maurice dressed in totally different, utterly Western armor, being a Roman commander and all. The point, however, is that people actually *living* in the period are apparently more openminded than some of us. This suggests to me a massive screwed up fantasy fandom.
I think you are far more charitable with medievals for far less cause than you are with other people in this thread. I love the medieval period, and there are all sorts of misconceptions about it especially in portraying its people as stupid, dirty, etc. However, I know of no particular evidence that they were any different in thier racial intolerance than anywhere else.
The real St. Maurice, if such a person existed, did not leave enough evidence behind for us to know how he dressed. If he really was from a Roman Legion drawn from North Africa, he probably used a style of armor appropriate to that (now largely vanished) culture. That might have been scale mail or chain mail or who knows. But even then, we can't really be sure because Roman carvings representing soldiers often seems to show the Legions in a sterotyped manner not intended to represent actual appearance but to convey simple ideas in much the same manner as the Catholic icons. We can't know what the Theban legion looked like, nor can we know if it was uniform in appearance.
I don't think anyone here would object overly to fantasy to unique heroes with an exotic origin in some alien cultures, whether that alien culture be Drow Elves or Saracen inspired African/Persian kingdom. Nor do I think anyone would object to a well realized cosmopolitan setting where different racial groups live side by side.
But the notion that these are inherent to historical D&D and not merely potentials rarely realized and certainly rarely emphasized is not I think very supportable. For one thing, if this were the case, it would not have been necessary to have analogue non-European settings like Kara-Tur and most of the map of the Forgotten Realms. There aren't analogue northern European settings because the core setting has always been primarily European in conception and execution. Even Eberron's core setting is to a certain extent industrial age Europe.
The point is that there is a vast difference between taking ideas for a variaty of cultures and integrating them into a campaign world, and superficially painting in a few non-white heroes solely for the sake of them appearing non-white to satisfy some self-appointed commisars of what is political correct. The former is interesting. The latter is neither interesting nor as respectful to anyone as it would like to pretend to be.
It is rather annoying that there is a double standard that a European centered fantasy setting is exclusive, but that Kara-Tur or Nyambe is not.
It's a problem with cultural attitudes that is deeply ingrained and needs to be corrected with analysis. Remember: This thread is actually about commercial representation -- or was before all the conceptual teleportation that's been invoked to keep alive the limp, sputtering flame of monoethnic ideas. Careful analysis should be *expected* of WotC, and we should *demand* an ethical, inclusive position, rather than one that simply panders to bias. This bias is a problem, but it's important to remember that it is almost never the result of malice. It's a culturally ingrained reflex.
