I used to believe that I was -ok- with multiracialism. Yet, the evidence from history is clear, I think Dachs will agree with me on this. Multi-ethnic countries do not last. They're unstable and conflict is more common. Now, I would like to believe that we can live in a harmonioous multi-racial society, thats what my good heart tells me. Yet a look at the evidence proves it is untenable. Humans have inbuilt irrational distrust, a fear of others who aren't the same as them. Thats how tribalism began at the dawn of time. Now, you can say to me we can overcome our instincts and I agree with you, we can do this with many other things. Yet, i think this may prove impossible beyond a tipping point. As long as their is one huge group, at least 90% of the population than the type of conflict i discuss will be very low and on the whole it will be peaceful. Expand that to four ethnic groups with 25% of the population and such a society will be unsustainable.
