Only just popped into the end of this thread to see how it was developing....and it looks like weird claims have been made for 'racial superiority'. Like the Loch Ness Monster and the Miracle at Fatima, racial superiority is a myth. It was adhered to out of a mixture of colonialism, naivety and supreme self-confidence before 1945. Since then the only people who drag it out and parade it to support hypotheses are charlatans, very bad and wicked sorts like the KKK, or the spectacularly ill-informed.
There is no empirical evidence to support notions of racial superiority. Anthropologists hesitate to apply 'race' as anything other than a very broad series of evolutionary responses such as skin colour and eye colour.
Bazwillrun has confused the complex interplay of geography, climate and resources with innate human superiority. I recommend any of Professor Jared Diamond's works Baz, a good read and very well researched eg 'Guns, Germs and Steel'.
