This ethnicity thing is very strange. The IQ variations excite great "racist" condemnations and overtones, but we appear to accept that Ethiopians can run the arse off whiteys at long distance, that average penis length does vary with race [unfortunately], that some races are rubbish at swimming, and so on and so on.
So why does IQ excite so much angst? In every professional competitive course that I attended I came second to a Chinese or a Singaporean. I also always lost at table tennis against them.
Fact. Get over it. It is not racist to point to demonstrable truths. Different races have different strengths but we all have to play to our strengths and cover each others' weaknesses. It is a small planet.
The biggest ****s I have known were white. The nicest people I have known were black.
So?
