I have my own theory, personally. I believe our minds are all based on a basic tribal set up. Of course, you'd have to prescribe to the theory of evolution, as well. The three basic types of pre-human would be child, adult, and outcast. The child learns to be an adult from the adults, and the outcasts scavenge on the outside of the basic society. The only reason this matters is because it's possibly ingrained in us that different is bad. For that kind of society, I imagine it would be. We may have moved on to bigger and better things, but the building blocks from that stage in evolution are still there. I have faith that eventually we'll grow past it, it's just gonna take awhile.
