When I was at high school I remember learning about "Heuristics" - which is a Psychology term describing the shortcuts our brains make to understand our environment without exploding from the sheer sensory overload of having so many visual things to input into our finite brains.
Apparently the concept came about from trying to teach computers to play chess - there were so many "assumptions" (or Heuristics) a human has to make in order to play chess that it made the chess programs alot harder to program on a completely logical machine.
Basically, if we took in the details of every leaf on every tree our brains simply couldnt cope with that amount of information AND simultaneously do anything else so it has to make shortcuts.
So if you think that our Brains are operating in this way it becomes clear that the better endowed the brain - the more able to cope with different sensory information it is - and the less likely it is to make primitive assumptions based on racial attributes, which would be more or less, glorified Heuristics.
Racism is the name for a slightly more complicated form of heuristics - when someone's brain cant quite understand that somebody with different racial characteristics than them might have ONLY THOSE differences, and no others and so the case for having any problem with them for just their Race is pretty weak and primitive.
I find this air of intellectual superiority much comfort when the Nazi Brown Coats hammer my skull with fence pailings full of nails. Right Kids!?
now can we stop oppressing our poor transistorized mates with this discussion and get them back to singing?
