Racism isn't something to build a roleplay around in PlaneShift. So it's simple: don't do it. You can avoid it and have an absolute blast. You can never step near it and build stories and worlds beyond usual imagination. Racism isn't a necessary part of the formula. Distrust is not racism. Disagreement on preferences is not racism. In Yliakum, although some races may be wary of others, they do not hate, discriminate, nor abuse.
But what
IS racism? Where's the point at which distrust/caution becomes racism?
If I have an irrational fear of the colour blue, I would thusly hate to be around Kran. Is it racist that I would request that all Kran stay away from me because of this fear?
How about if my family was massacred by an enkidukai when I was three years old? Psychologically, a fear and hatred of anything that resembles an enkidukai would most likely arise. In fact, it would be bizarre if I
didn't have an inherent distrust for enkidukai.
And that's just an extreme case.
Little kids on the playground are constantly discriminating against each other for reasons far less than one having red skin and horns

If there was a little diaboli kid in a Xacha village, the Diaboli would be picked on to death. It's not necessarily a race thing, just a difference thing, like if the horns were braces.
The point is, if we're talking about general, grand-scale political racism, then I agree it shouldn't exist. But if we're talking about individual racist ideals, then that's just illogical. So long as people are able to make their own choices, mentally, there will be people who choose to hate.
If this concept gives you difficulty, I weep.
Hehe, it's not that I
like hate/abuse/discrimination, it's just that I'm very skeptical as to how any society can exist without it. Even birds have a 'pecking order', and animals are constantly killing each other over territorial disputes.
