Okay mouse! The word R has been mentioned! Sneeze for us will ya? XD
Mmmmm. Interesting quote Blaidd. However, would it apply if the orc tribe lived for centuries near a human kingdom of black people and then all of a sudden they encounter white people. Will the black decide to unite with the white and bash the green, or would they rather interact with the orcs because they have known them already? Many things are possible.
For example, in my world, I have yet to decide if Kastosians will at first not suspect even more black people than orcs. I guess there is a conscient racism on one hand and on the other a suspicion of the unknown which would be more xenophobic... First contacts are always harder because you don't know how to react or what to make of something or someone you never saw. What's funny in my novel project is the long waited for and prophesized Emperor who will lift once more the banner of the Kastosians (a white nation) is actually a black noble from a kingdon across the ocean. At first, almost everyone will think he is not human, especially because he comes with a crew of humans, dwarves, and elves. But afterwards I think I will have a feud between the kastosians themselves. On one side, those who will let go of their first reaction and accept that though he is black he is indeed as human as everyone, while the bad guys will go from a simple fear of the unknown to a hatred of what they do NOT wish to know. In all of that chaos, they will have also to learn to accept other races. Hey, actually I like that idea quite alot. In fact, that confrontation has to take place if I want to change the Kastosian Empire's view on orcs so they may actually later on even force an alliance with another empire further south the continent which is a mix of humans and orcs.
In other words, the northern continent of Evozen will never see a single black man or woman untill the appointed time has come, a whole context in which they will have to seek more allies and even overcome past hatred and work with goblins and orcs. By having racism of white against black coming so late, it may actually allow those who will reject racism to even go further and accept other races. If I do that too soon, the movement for acceptance of other races wouldn't be strong enough. So the comming of a black human will bring a reality which was untill then between races, inside humankind, and the solution found within humankind would afterwards jump to the in between races. We don't need star treck to have a crew with different races.
How does that sound? Would that justify afterwards a world in which several races can live without destroying themselves?
