Look, I know that there are many factors that contribute to these things, but consider the achievements of the Europeans (which, as I know, is comprised of many different ethnic groups), and those of most other cultures. I don't look at individuals as being inferior, so much as their culture and how they manage to represent it. If a black man robs a bank, I will not be biased against him, but if a vast majority of bank robberies were committed by black people, I would certainly develop some level of distaste for black people, even if only on a subconscious level. But since we live in a world where a sense of cultural guidance is being deteriorated and neglected, I have little opportunity to develop these slight biases. My only option, therefore, is to turn to history. Historically, who has dominated the world? Historically, who has produced the most notable cultural works, scientific achievements, and lasting monuments? How many great civilizations can I name from each continent?
When I finish reading 'Guns, Germs, and Steel,' I'll give you a more straightforward answer.
