China and USA, who depends on the other more and why? | It's pretty mutual. That's why you always laugh when people talk about China saber rattling or some 'impending war with China'.

If we attach certain personalty traits/ skills and abilities to particular breeds of dogs, then why are we wrong to attach them to particular groups of people? | We aren't different breeds of people. There are very few "purebread" people, and once you go back about a thousand years, there basically aren't any.
